The Onyx Boox Poke 4 Lite does not come with a case, to keep prices low. However, if you want to protect your e-reader from the rigors of the world, you will want to buy a case. You insert your e-reader into the case and flip the case closed and it will attach with a clasp. This will ensure that it does not fall out and is easily transportable during the commute, at home or going to the beach. The cases are available in a dark grey and cute meow.
