New, Unused Color: White Material: Plastic Easy to assemble! Simply install according to the photo instructions. The last screw can be attached if needed (optional). You can adjust the sensitivity of the rotation with the screw on the top of the inner axis. If the rotation is too fast, adjust by turning the screw counterclockwise. If you are concerned about slipping during use, please secure it by applying double-sided tape to the bottom. Since this is a handmade item, there is no original packaging. We will carefully package it to prevent damage during shipping. We also have black color and panda design products available. Thank you for viewing.
