Apple Pencil Rubber Tip

Hi

I really love the Apple Pencil that is used with the iPad Pro for sketching or drawing. My question has to do more with the tip of the Apple Pencil, which at times is kind of awkward when I sketch. I find that it's too slick on the iPad's glass top. Guess I'm looking for something with a little more traction. Does Apple make a rubberized tip or is there a third party that sells one? Thank you. -Kd
