DoggyMan Stay-at-Home Bowl

I received this item on Mercari, but my child was scared of the timer's sound, so they couldn't use it. I am selling it because of this.
The box and instruction manual are not included.

I plan to ship via standard mail.

This is an Orusuban (stay-at-home) feeder that opens automatically when the timer goes off. Capacity: approx. 220g of dry food. Timer: up to approx. 48 hours.
