Weapon name: Mini Wallet
Description: This wallet "ate" the Doa Doa no Mi which lets the owner store more/bigger items that seems impossible to fit inside because at the bottom of the wallet is a portal or a door that leads to a storage room somewhere in the real world. However, the limit is the space of the storage room that the door leads to, and if the storage room is emptied out or robbed, then obviously you cannot pull out items from the wallet because there isn't anything in the storage room.
Weapon special abilities: Carries more than usual without the usual limit of space and weight.
