You Inventory is accessed by clicking "Home" and then "Your Inventory", and it is where all the items you own are stored. From this page you can transfer, sell, auction, trade them. You can also use any usable items (such as Potions and Pears) and equip any equipable items (such as accessories, wallpapers, and foregrounds). You can do this by clicking the item and selecting the option you wish to carry out.
