Thank you for viewing! Please let me know your desired angle (40°, 50°, or 60°) via the transaction message after purchase. 30° is also available on another page. 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 between the stand and a plate (magnets and iron plates are built-in, and unevenness is used to increase adhesion). It further tilts the mouse from the standard 20° angle, allowing for work at a more natural hand angle. * A stick is included that can be used when removing the ball, and it can be stored by being held in place by 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. * 40° is popular, followed by 50° and then 60°. As the angle increases, the height of the ball also increases, so you may need to adjust the height of your hand with a cushion or similar. Made in Japan Color: Black Materials: Plant-based resin (bioplastic PLA), iron, magnets \* Please note that this product is manufactured with a 3D printer, and there may be layering unevenness or stringing on the surface. \* Only the angle adjustment stand is included; the MX ERGO body and metal plate are not included.
