Thank you for viewing. Please refrain from price negotiations. Thank you for your understanding. --- This is an angle adjustment stand specifically for the Logicool MX ERGO and MX ERGO S. It attaches by sandwiching the MX ERGO body and the plate (it incorporates magnets and iron plates, and has unevenness to increase adhesion). It tilts an additional 10° from the standard 20° inclination angle to 30°, allowing for work at a natural hand angle (this product is 30°, but there are also 40, 50, and 60° lineups). - A stick is included that can be used when removing the ball, and it can be stored by being fixed with a magnet when not in use. - It has a smooth and simple design that matches the shape of the MX ERGO. - The stand will not fall off even if you lift the trackball. Made in Japan Color: Black Material: Plant-based resin (bioplastic PLA), iron, magnet Weight (including the ball removal stick): 30g Overall height (from the top of the ball to the ground): 66mm *Please note that this is manufactured with a 3D printer, and there may be unevenness and stringing on the surface. *Only the angle adjustment stand is included; the MXERGO body and metal plate are not included. #mxergo #mxergos
