Thank you for viewing. This is the "Tatakite Pikapika Drum" educational toy released by Toyroyal. According to the manufacturer, the main body size is 152mm wide x 160mm high x 152mm deep, and it requires 3 AA batteries. It was played with regularly from around 1 to 3 years old, so there are some scratches and minor marks, but I think it can still be enjoyed. Operation has been confirmed, but we are not responsible for any malfunctions due to impact during shipping, so please purchase only if you understand this. Below is an excerpt from the manufacturer's description. ※Target age: 10 months and up [Drum sounds and lights that shine] When you hit the pad with the drum upright, you can enjoy the sound and lights! There are 3 sound modes: <drum sound>, <multiple drum sounds>, and <sound effects>. The lights gently shine in 7 random colors. Press the melody button and you'll hear 3 fun melodies! When the melody is playing, hitting the drum will make a sound. (3 songs: Heigh-Ho, The Bear Went Over the Mountain, The Music Man) When you roll the drum sideways, a melody will play and the lights will shine! (1 song: London Bridge) The edge of the drum is made of a soft material that is resistant to scratches even when rolled. There are 2 volume levels to choose from.
