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 uses magnets, iron plates, and protrusions to attach to the MX ERGO body by sandwiching it with the plate. It further tilts the standard 20° angle to 30°, allowing for work at a more natural hand angle (this product is 30°, but there are also 40°, 50°, and 60° options). - A stick for removing the ball is included, and can be stored securely 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 Materials: Plant-based resin (bioplastic PLA), iron, magnets Weight (including ball removal stick): 30g Overall height (from the top of the ball to the ground): 66mm *Please note that this product is manufactured with a 3D printer, and may have surface irregularities such as layering and stringing. *Only the angle adjustment stand is included; the MX ERGO is not included. #mxergo #mxergos
