Works. There were two spikes of different sizes. Very soft rubber foam. I was hoping for a stiffer rubber tip on the pen. That will work. It looks good. I like the black pen. The quality is pretty average that I could find here, but I like it. More like business. He came up with a few extra tips. Accuracy is a little below average, you have to press a little harder for it to register. The letters on the handle are different from the ones in the picture I ordered. I will use them.
