This is a Sanrio Cinnamoroll children's wristwatch. There is no instruction manual, but it has a built-in battery and runs automatically. Operation has been confirmed. The entire watch is a see-through blue, and the white Cinnamoroll is very eye-catching and cute. This is a new, unused item, but it has been stored at home by a private individual, so please refrain from purchasing if you are sensitive to such matters. Thank you for looking.
