Thank you for viewing. I purchased this about two years ago and used it for about a year, but I'm selling it because I no longer have the opportunity to use it. The anti-slip pad on the right-side height adjustment stand is missing. Please refer to the images for the overall condition. I will clean it as much as possible before shipping. - Brand: Logicool - Connection Type: USB connection (wired) - Color: Black - Model: G512 - Key Type: Mechanical key (red axis) - Dimensions: 44.5cm length x 13.2cm width x 3.6cm height Thank you for viewing.
