I purchased this new for my child, but it ended up not being used, so I am selling it. I opened the package only to confirm that it operates correctly (it works perfectly ◎). Otherwise, it is like new. The 3M tape provides strong adhesion, so you can rest assured. There was no original instruction manual, so please refer to photo 2 for usage instructions. 【Product Description】 Safe and secure!
