Item Box

Item Box is a dimensional space which YGGDRASIL players use to store their items.

Appearance
A palm-sized dark, purplish portal that opens up in the fabric of space and time when a player put their hand in.

Abilities
Item Box allows people to store or place various sorts of items within. It seems to possess a limitless amount of space. However, the limit to its capacity is 500kg. Extremely useful for storing different items needed based on the situation. It is possible for a high level thief to steal from it, though the limit of loot would be one or two items per player.
