I LOVE these things. They create the perfect friction and really help me draw with precision. (I have trouble drawing with slippery tools like pencils, and this is how I feel with a nibless apple pencil). The only downside is that I go through about 5-7 of each drawing. I don't apply a lot of pressure when I paint, but they always snap at the tips pretty quickly. But there are so many of these in a small package, and they're at such a good price that I don't even mind. Also, it's fun to change the colors.
