Soft toy enthusiast here. I want a 2-layer sleeve that's super soft on the inside with a harder (but not hard plastic) TPE outer shell to enhance tightness. So basically the opposite of all the 2-layer sleeves for sale. I've attempted to create my own, but have never had much success.

Does this exist? If not, is it a demand issue? Maybe a technical issue?

Anybody else in this boat?
