Closet

From Wild World Wiki

Closets are items of furniture that have a specific purpose in AC:WW. They can be used to store items in a small space. Most closets are one square by one square, and all can hold a maximum of 90 items in six sections. Closets are not stackable, so if you have more than one closet in your house you will still only have 90 spaces for items, and items will appear and disappear from both closets as you add and remove them.
