Twin bell clock featuring a Mickey Mouse design. The alarm sound is probably a bell sound. It seems the mechanism is that the central protrusion swings left and right to ring the bell. I opened it to check the contents. Please understand. When shipping, I will ship the clock itself, blister pack, and instruction manual without the outer box, so please understand. - Brand: Disney - Model Name: Mickey Twin Bell Clock - Design: With Mickey Mouse illustration Requires one AA battery (sold separately). - Color: Silver/White - Material: Plastic/Metal - Target age: 12 years and older Thank you for viewing.
