This is a storage/travel case for the Kindle Oasis 9th Ed model CW24Wi. The kindle is held in place by magnets. I like the slim form factor of the caseless Kindle, so this case is designed to keep the screen safe, while being easily removable. The case holds onto the Kindle with four 6mm by 3mm circular magnets. There are recesses for the various buttons and a cutout to allow for charging while in the case.
