Backpack of small

This bag is a magical backpack for the smallest of creatures, it looks like a normal backpack that you would find anywhere else in the realm, just shrunk down. It has a magical property that makes so I holds the same as a normal backpack, 1 cubic foot / 30 lbs. of gear, while only ever being no more than 10 lbs. 

When taking things out or putting things in, of any size, the mouth of the bag makes room for that item.
