◆ For Hamsters Multi-Water Supply Tank Harmony House S This is a set of 3 items: the water tank, the house, and the toilet. I'm selling these because they felt cramped when I put them in the case I already had. The items have only been opened and set up inside the case once. Basically, they haven't been used. Only the toilet was opened by a child, and it doesn't have a case. The box is torn from when it was opened, so please be aware of this if you are looking for a box in good condition.
