Your Colossal Closet
From A KoL Wiki

Your Colossal Closet is a furnishing located at your Campground.
Notes
- Everyone starts the game with a Colossal Closet at their Campground.
- The Colossal Closet can be used to store as much meat and items as you like (to a maximum of 16,777,215 units of a single item); these can then be pulled back out again whenever you like.
- All meat added to Your Colossal Closet in excess of 2^32 (4,294,967,296) will be instantly deleted.
- Upon ascension, all meat and items stored in Your Colossal Closet are transfered to storage (except for Quest items, which are lost).
- Your Colossal Closet itself is not affected by ascension; you do not have to re-obtain it in your next incarnation.
- Closeted items are not safe from PvP.
- Pressing the + button more than ten times will display the message "eleven is enough"
- If you already have 16,777,215 units of a single item in your closet and attempt to put another one in it yields the message "1 of Item *NOT* moved from inventory to closet. Something went wrong." and you lose the item you tried to transfer.
