Anna Sui Multi-Case This is a novelty book bonus from about 15 years ago. At the time, I bought it because I heard it was the perfect size for an iPad, but I only used it at home with a silicone cover on, so I haven't used it. 27 x 21 x 4 cm It's about the size of a clear file. It also has dividers inside, so I think it's convenient for carrying accessories like the Apple Pencil.
