During the most recent testing, there was sort of a brainstorming going on in the Help Channel about gifting items to other glitches. One idea seemed to generate the most excitement - the ability to gift-wrap a storage bag for the sole purpose of gifting to other players, primarily to those hard-to-find Level 1 glitches.
A Gift-Wrapped Storage Bag would be able to stack 1 within another Storage Bag, but itself could NOT be used for storage while in it's gift-wrapped state. The glitch receiving the Gift-Wrapped Storage Bag could then unwrap it, and then would behave as a normal Storage Bag.
