Automatic Water Dispenser and Feeder Set for Dogs and Cats

I accidentally purchased two sets, so I'm selling one.
The box has been opened once, but the contents are unused.
I purchased it for ￥2,980 on Yahoo Shopping.

★ Automatically dispenses food and water using the principle of gravity.
★ Detachable design for easy installation and removal.
Easy to clean and convenient to wash.
★ Automatically refills water when the level gets low and stops at a certain point, making it very convenient.
★ Made of high-quality PP material, it's cute and transparent, allowing you to easily see the contents and monitor the food level.
Suitable for cats, dogs, rabbits, as well as small animals like hamsters, ferrets, and guinea pigs.
