Protecting One’s Books

I woke up with an idea this morning. I’m rather particular about keeping things in good nick, and books are certainly no exception. It’s always tricky to pack a paperback just right into a bag so that its risk of damage is as low as possible. Then it hit me; why aren’t there any small portable paperback cases readily available?

A quick hunt on Google yielded big portable cases, but nothing small enough to fit in a bag. If humanity can manage this for a banana, surely we can do the same for books.
