Here are some ROCK BEAT drumsticks. I feel like a drummer! It operates using 4 batteries. I used them once and have kept them stored away ever since. When music plays and you hit these sticks, the tips light up with electronic sounds. You can play various sounds like snare, tom, and cymbal, making it feel like you're playing a real drum set♪ These are used items, so I appreciate your understanding. There are no noticeable scratches or stains, and they are in relatively clean condition. [Product Condition] No noticeable scratches or stains [Color] Silver系 (Silver-toned) [Size] Approximately 35 cm in length Thank you very much.
