[GBGW] I want to know about how many items can be contained in the Item Box.
For default 1 slot setting in the Item Box, up to 999 possessed items can be contained and can be received up to 50 slots.
* For example, if you have 1,000 coins, you will use 2 slots in the Item Box.
If there are no open slots for possessed parts, the remaining parts will be sent to Gift Box.
In this case, in order to receive the item, it is necessary to arrange the possessed items or expand the Item Box.
