This is a rotating stand I purchased on Amazon for 2880 yen. I used it for a while to hold a monitor. There are three scratches, but overall, it's in good condition. --- The following is from Amazon: Perfect for sharing the screen of a computer, notebook, or other display. It uses roller bearings to allow smooth rotation even with heavy items placed on it. Anti-slip pads on the bottom prevent the rotating stand from slipping, allowing for stable use of your devices. Anti-slip rubber pads are included to stick on top if the device placed on it is prone to slipping, allowing for stress-free use. *This does not guarantee the operation of all devices.
