GJY Silicone Case for Surface Pen Platinum (Pro 5, Pro 6) (White+Blue)

The surface pen is nice but very thin and slippery. I needed something t help me hold on to it. This works great. Once you get it on, which is admittedly a bit tedious, it stays where you put it and has various textures for grip. It appears to be a quality silicone material and feels good in your hands.
