If you use a Wacom tablet I'd recommend these replacement felt nibs, I recently fitted some on my Cintiq pen and they make a big difference, they make the pen feel a lot more natural and responsive, similar to a soft pencil or marker pen. Only down side is that they ware out much fast then the original plastic ones.

Doubt I'll be sporting one of these babies though, bit to much like a cyborg golf glove !
