A DIY bed mobile kit. No batteries required, the hand-cranked music box plays a beautiful melody. The song is "You Are My Sunshine," and its operation has been confirmed. I used it with handmade amigurumi attached. Recommended for those who want to prepare a handmade mobile for their baby. You can easily change the hanging items, making it easy to use for siblings with different atmospheres. I used it hanging from the ceiling, so only the main unit in photo 4 was actually used. The bed fixing set in photo 5 is unused, but there was some discoloration on the back of the screws from the time of purchase. Please check photo 6. It will be in a part that is not visible when attached, so I think it can be used without any problems. Easy to install, no screws required. It rotates freely and can be securely attached to a bassinet. It's a type that attaches to a baby bed, is easy to install, requires no screws, and is easy to change the installation location. Please consider this item, understanding that it is a used product.
