Heart Backpack

You have to say Heart Backpack in order to buy it from Valentina. She only has one left and as such any one character can only buy one from her every year. People can sell these backpacks for a lot of money, because you can only buy one per character each year.
See Backpacks for general information regarding backpacks.
