HOMESTAR AQUA with waterproof function, a Milky Way projector that projects 10,000 stars. Turn off the bathroom lights and watch the slowly rotating stars while listening to the sound of "splash...splash..." You will feel relaxed and healed in both body and mind. It's also nice to use with children. Both the main unit and the outer box show little signs of use. The cushioning material inside the box, which prevents the main unit from rattling around, is slightly creased in some areas. There are absolutely no issues with the operation of the main unit, so please rest assured. It comes with Panasonic batteries with an expiration date of 2028, so you can use it from the day it arrives. - Brand: HOMESTAR AQUA - Waterproof function: Waterproof - Function: Milky Way projection - Number of stars: 10,000 stars - Light source: LED - Color: Black It comes with Panasonic batteries with an expiration date of 2028, so you can use it immediately.
