This pen grip is a game changer for osu, if I could link a clip of before and after I would. My aim became sharper and my pen doesn't slip anywhere near as much as before. Would recommend if you have any issues with your pen slipping while in a map.

I got the Blueberry(Slim) after emailing Korilak and asking about options for the Wacom Pro Pen 3. First time attaching the grip is pretty difficult, after that it gets really easy. It first felt like it excessively covered the pen and over time it shrank(pictured) down and now a bit of the pen is exposed. It moderately helped my issue with gripping the pen too hard, but there was definitely a learning curve for me of a ~week of playing to get adjusted. I had only used a bare pen before this without ever exploring options for grip tape.

Overall I enjoy this grip but I'm might purchase one that fits my grip more
