Pure Crystal new pump, model number P-4, and a new adapter are included. The main unit is also shown in the photo, but it was only used for about 3 days with water in it. The listed price is for the pump and adapter, but if you would like the main unit as well, I will sell it for an additional 600 yen. It's a half-circle shape that can be placed against a wall, so it doesn't take up much space. It can also be attached to a cage. The new fixing device in the photo is also included. Please let me know in the comments.
