A few weeks ago I asked here if anyone knew of a packing sleeve for my portenzo/octavo/treegloo. I got a raft of crap about being anal, I didn't care then, and don't care now what anybody writes. But if you are packing a bookcase and want to protect against your toothpaste breaking, here's one that works perfectly - very slightly padded and fits snug but not tight. Order the "small" one.
