Ergonomic Design: You can adjust the HUION ST300 stand from 20 to 60 degrees to fit your workspace, which relieves strain on your neck, shoulders, and back and provides the ideal viewing angle for typing and drawing. Carry it Around: The HUION ST300 stand is simple to fold into an 11mm thin, flat piece that you can carry around in your bag. Stay in Position: The ST300 stand's anti-slip mats on the aluminum alloy surface can help you prevent needless skidding and keep your device firmly in place. Additionally, the concealed stopper can hold your gadget in place. Universal Usage: The original stand for Kamvas 12/13/16 (2021) and Kamvas Pro 12/Pro 13 is the HUION ST300 stand. It fits as well.
