The collected wisdom of Deckard Cain's life is written down in the Book of Cain. The artwork of the Book of Cain was the inspiration for the Demon Sleeve. It also features a stylus holder and is the perfect supplement to Cain's Bag. This Tablet sleeve is designed for up-to 10" tablets with a 4:3 aspect ratio like the iPad 1-4 and Air series. Additionally, this sleeve comes with a elastic loop on the inside to hold a stylus like for example the Apple pencil or similar devices.
