TFY E-Reader Protective Pouch Bag with Zip Closure, Plus Bonus Hand Strap Holder for 6 inch e-Readers - Kindle 6 inch/Paperwhite/Voyage/Oasis 6 Inch/Nook GlowLight Plus/Kobo Aura/Touch 2.0

This fits the Kindle Paperwhite 2018 (10th gen) perfectly, even with the grip attached. I have not tried other grips, but I like this one. Its snug, but it requires no effort to hold onto the device, and can definitely be used securely while lying down. I imagine it would even stay attached to your hand if you fell asleep. The inside of the pouch is soft and cushiony, just like the photos. The outside pocket provides just enough space for the budget Bluetooth headphones that I paired to the Kindle for listening to audio books. Its all now ready to go for travel!

Perfect

This case arrived promptly as expected and fits and protects the Kindle Paperwhite E-reader perfectly, the included Bonus Hand Strap Holder makes holding the e-reader much more comfortable, especially for my older slightly arthritic hands.
