A Belt Pouch holds up to 5 items.
A player can only equip 1 Belt Pouch at a time.
The capacity can not be increased with a Rune of Holding.
You can unequip a Belt Pouch by dragging and dropping it into an inventory slot, provided it is empty.
A Belt Pouch, as a Backpack or a Bag, can be Dyed, often coloring in a somewhat different color than one would expect. The Belt Pouch's natural color is brown. Dyeing will not change the appearance of the character, but will only change the inventory picture.
