These sleeves are made out of a neoprene material! This one is slightly different than the other designs because on the one side it says "busy reading" but on the other side, it has a pocket with a cute pink and white star pattern on it! :) Each has 2 zippers for closing on the top, and has a pocket on one side with a pink accent trip on the edges. Dimensions: 7 x 9 inches Can fit the kindle paperwhite, kindle basic, and an ipad mini! (slightly larger than the fabric kindle sleeves)
