It's one of the more unusual iPad cases we've yet seen: Brenthaven's Bill-Fold Sleeve ($35) is pitched as a product with 100% recycled billboard material on the outside, a soft faux suede interior, and a white-on-black color scheme. Both sides of the sleeve are open by default, using Velcro to fold closed on each side as you prefer, creating what looks like a bulging pouch when completely sealed. A Brenthaven tag on one side is its only branding.
