Belt of Storage (Medium)
This seemingly normal belt is made of thick leather and has a rather large belt buckle. When worn around the waste, small extradimensional pockets will appear, but only they are only visible and usable to the character wearing it. There will be 8 of these pockets, and each one has a content weight limit of 100 pounds and a volume limit of 30 cubic feet. No matter how much is stored in these pockets, it will not increase the weight of the belt.
