Kindle cases
The best Kindle Paperwhite case depends on how you use your device. For daily commuters, a slim folio case with magnetic auto sleep/wake is ideal — it protects the screen during transport and preserves battery automatically. For home readers, a lighter handheld case may feel better in the hand during long sessions.
MTMoiss Kindle Paperwhite cases are precision-built for the 11th generation Kindle Paperwhite (2021) and the Signature Edition, with rare-earth magnets aligned to Kindle's sleep sensor.
Yes. All MTMoiss folio cases for Kindle include a built-in rare-earth magnet positioned to activate Kindle's magnetic sleep/wake sensor.
Opening the cover wakes the device immediately. Closing it puts the Kindle to sleep automatically. Over time, this can noticeably extend battery life compared to manually managing sleep mode.
A detachable magnetic Kindle case is a two-part system:
Part 1 — The back shell: A rigid or semi-rigid case that snaps onto the back of the Kindle and stays attached.
Part 2 — The front cover: A magnetic folio that attaches to the shell and can be fully detached for reading.
This design gives you the best of both worlds — full screen protection when stored, and a bare-device feel when you want to read without the front cover.
Yes. MTMoiss Kindle Paperwhite cases are designed for the 11th generation Kindle Paperwhite (released 2021, model number B09TMF6741) and the Kindle Paperwhite Signature Edition.
They are not compatible with the 10th generation Paperwhite (2018) due to dimensional differences. Each product listing specifies its compatible models clearly.
No. The Kindle Scribe has a 10.2-inch display — significantly larger than the Kindle Paperwhite's 6.8-inch screen. The two devices have entirely different dimensions and require separate cases.
MTMoiss makes dedicated cases for the Kindle Scribe with stylus-compatible design and precise port/button access.
MTMoiss slim folio cases add approximately 4–6mm to the closed device thickness. The total weight added is typically under 80g, keeping the Kindle light enough for comfortable one-handed reading even in a case.
Kindle case: Attaches to the device permanently. You read with the case on. Provides continuous protection and (with a folio case) screen protection when not reading.
Kindle sleeve: A pouch or pocket that you slide the Kindle into for storage. You remove it before reading. Better for those who prefer a naked device during reading but want storage protection.
No. Using a third-party case does not void your Kindle's warranty. Amazon's limited warranty covers hardware defects in the device itself, regardless of whether a case is used. The warranty would only be affected if the case caused direct physical damage to the device.
On your Kindle, go to Settings → Device Options → Device Info. The model name appears at the top of the list. Alternatively, the model number is printed on a label on the back of the device (e.g., "Kindle Paperwhite, 11th Generation").
For Kindle Scribe, the model name is shown on the About screen in Settings.
MTMoiss slim cases are thin enough to be compatible with Qi wireless charging pads — you typically do not need to remove the case to charge. However, thick wallet cases or cases with metal elements may interfere with wireless charging. The MTMoiss folio case for Kindle Paperwhite Signature Edition is wireless-charging compatible.
Kobo cases
The Kobo Libra 2's asymmetric body — with physical page-turn buttons on one side — requires a case designed specifically for its shape. The best Kobo Libra 2 cases have precise cutouts for all buttons, a magnetic closure aligned to the Kobo sleep sensor, and a slim profile that doesn't disrupt the device's natural one-handed reading feel.
No — these are different devices with different dimensions:
Kobo Clara HD (2018): 157 × 109 × 8.3mm
Kobo Clara 2E (2022): 166 × 113 × 8.3mm
Kobo Clara Colour (2024): 166 × 113 × 8.3mm (same body as 2E)
The Clara 2E and Clara Colour share the same dimensions, so cases for one typically fit the other. But Clara HD cases will not fit the newer models.
Yes. MTMoiss folio cases for all supported Kobo models include a magnet precisely positioned for each device's sleep sensor. This applies to Kobo Libra 2, Kobo Clara 2E, Kobo Clara Colour, Kobo Sage, and Kobo Elipsa.
Auto sleep/wake must be enabled in Kobo settings: go to Settings → Energy Saving → Sleep Cover Detection and ensure it is toggled on.
The Kobo Sage has an 8-inch e-ink display in a device measuring approximately 196 × 136 × 8mm. It supports Kobo's Stylus for note-taking.
MTMoiss makes a dedicated Kobo Sage case designed for these exact dimensions, with a stylus holder loop and magnetic sleep/wake support. It is not compatible with Kobo Libra (7-inch) or Kobo Elipsa (10.3-inch) cases.
No. The Kobo Elipsa and Kobo Elipsa 2E have different physical dimensions and button placements. Always buy a case listed specifically for your model.
The Kobo Libra Colour (2024) uses a colour e-ink display; the Kobo Libra 2 (2021) has a monochrome display. Both share the same 7-inch form factor and asymmetric body with physical buttons — cases for Kobo Libra 2 fit the Kobo Libra Colour, and vice versa.
Handheld / grip case: Wraps the back and sides of the Kobo. No front cover. Designed for comfortable one-handed grip during reading. Lighter and less bulky. Does not protect the screen when not reading.
Folio case: Includes a front cover that folds back during reading. Protects the screen at all times. Slightly bulkier but better for transit and bag carry.
For commuters: folio. For home readers with long sessions: handheld.
Yes — especially for daily use. Kobo screens are glass and can scratch or crack without protection. A folio case protects the screen in transit, and auto sleep/wake cases can extend battery life noticeably, which matters on longer reading trips.
Kobo devices also have relatively exposed USB-C ports compared to Kindles — a case that covers the port area when not in use helps prevent dust and debris build-up.
On your Kobo device, go to Settings → Energy Saving. Enable Sleep Cover Detection (sometimes labelled "Cover Detection" depending on firmware version). Once enabled, opening the case cover wakes the device; closing it triggers sleep.
If sleep/wake does not activate, ensure the case magnet is properly aligned with the device's sensor — the sensor is typically located on the left side of most Kobo models.
Yes. MTMoiss offers cases for:
reMarkable: reMarkable 2, reMarkable Paper Pro — folio cases with stylus holder and magnetic sleep.
Boox: Boox Palma (pocket-sized), Boox GO Series — each with device-specific precision fit.
Also available: Pocketbook, Bigme, and Viwoods device cases.
General questions
MTMoiss makes precision-fit cases for the following devices:
Kindle: Kindle Paperwhite (all generations), Kindle Scribe
Kobo: Kobo Libra 2, Kobo Libra Colour, Kobo Clara 2E, Kobo Clara Colour, Kobo Sage, Kobo Elipsa, Kobo Elipsa 2E
reMarkable: reMarkable 2, reMarkable Paper Pro
Boox: Boox Palma, Boox GO Series
Other: Pocketbook, Bigme, Viwoods
Simply match the case to your device brand and model. Kindle cases only fit Kindle devices; Kobo cases only fit Kobo devices — they are not interchangeable. Within each brand, always select a case listed as compatible with your specific model and generation.
Our buying guides walk through the differences model by model if you're unsure which device you have.
Folio case: Front and back coverage, magnetic sleep/wake. Best all-round protection.
Detachable magnetic case: Back shell + removable front cover. Flexible: protect during transit, read without the cover.
Clear case: Transparent back case showing the device colour. Minimal, lightweight.
Sleeve: Protective pouch for storage. Device is removed to read.
Handheld / grip case: Back and side protection, optimised for single-handed hold.
E-readers from Kindle and Kobo contain a Hall effect sensor (a magnetic sensor) positioned inside the device body. When a magnet in the case cover passes near this sensor — as the cover is closed — the device enters sleep mode. When the cover opens and the magnet moves away, the device wakes.
The magnet position in the case must be precisely aligned with the sensor location for each specific device model. This is why generic or universal cases often fail to trigger sleep/wake correctly.
Yes. MTMoiss slim folio cases are designed to add minimal bulk — the total device-plus-case weight remains comfortable for one-handed reading for most people. For extended sessions, a detachable case or handheld case may feel lighter since the front cover can be removed or folded fully back.
Yes. MTMoiss cases are covered by our standard return and exchange policy. If your case arrives damaged or with a manufacturing defect, contact us at joewan2020@163.com and we will arrange a replacement. See our full Return & Exchange Policy for details.
Orders are typically processed within 1–3 business days. Estimated delivery times vary by destination — standard international shipping is typically 7–14 business days. Tracking information is emailed once your order ships.
A tablet sleeve designed for a similarly-sized device can work for storage, but a purpose-built e-reader sleeve or case will fit more precisely and offer better protection. Generic tablet sleeves are often designed for 10-inch devices and will be too large for 6–8 inch e-readers like Kindle Paperwhite or Kobo Libra.
The five qualities that define a good e-reader case:
1. Precise fit — designed for your exact device model, not a universal fit.
2. Auto sleep/wake — magnetic closure that activates your device's sensor.
3. Lightweight construction — should not significantly increase holding weight.
4. Screen protection — front cover or recessed bezel that protects the glass.
5. Full port access — USB-C, headphone jack, and button cutouts that line up exactly.
MTMoiss was founded in 2024 with a focus exclusively on e-ink reading device accessories. Unlike general electronics accessory brands, all our cases are designed specifically for e-readers — from the magnet placement for sleep sensors to the lightweight construction suited to long reading sessions. We cover Kindle, Kobo, reMarkable, Boox, Pocketbook, and other reading-first devices.
Care & materials
MTMoiss cases feature:
Exterior: PU leather (polyurethane leather) — durable, water-resistant, and available in a wide range of designs. It resists everyday scuffs and minor moisture.
Interior lining: Soft microfibre — gentle on device screens, prevents micro-scratching.
Magnets: Rare-earth (neodymium) magnets, embedded in the spine and cover, precisely positioned for each device's sleep/wake sensor.
Exterior (PU leather): Wipe with a soft, slightly damp microfibre cloth. For marks, a small amount of mild soap on the cloth can help — wipe off with a clean damp cloth afterwards. Allow to air dry.
Interior (microfibre): Use a soft dry cloth to remove dust and debris. Avoid liquid on the interior lining.
Avoid: Harsh chemicals, alcohol wipes, bleach, abrasive cloths, or direct heat (hair dryers, direct sunlight for extended periods).
The PU leather exterior provides light water resistance — it will withstand minor splashes and light rain without damage. It is not waterproof and should not be submerged.
Note: even for the waterproof Kindle Paperwhite (IPX8 rated), adding a case does not extend or change the device's water resistance rating.
No. E-readers use e-ink displays that are not affected by magnets. The sleep/wake sensors in Kindle and Kobo devices are specifically designed to detect the type of magnetic field used in cases — this is a built-in feature of the device, not an external workaround.
The magnets will not damage the e-ink screen, internal storage, or any other component of your device.
With regular daily use and proper care, MTMoiss PU leather cases typically last 2–3 years before showing significant wear. Patterns and colours printed on the exterior will maintain their vibrancy with proper cleaning. Avoid prolonged exposure to direct sunlight, which can fade any printed design over time.
