Backpacks

Backpacks (Slimefun)
Backpacks are a collection of utilities in which you can store items. When you initially open a Backpack, it gets assigned a UUID. The UUID's format is basically this:

(Player's UUID)#(Number of Player's backpack)

The Backpack's restrictions are that you cannot name them, and put backpacks into other backpacks, as that would be overpowered.

NOTE: When you open a backpack, you can NOT upgrade it anymore.

The Small Backpack can store up to 9 stacks of items.
