Great product, very happy with the nibs.

At first I was concerned if they would work for my Intuos 3's grip pen, but looking over all the options I'd say most of Wacoms pens would be designed to (at the very least) take the basic nib types. The pack also came with a handy pincer to help remove the old nib. Very cool.

Don't know why the black nibs are more expensive than these white ones – they work perfectly – don't be fooled by the size 99% of the nib goes inside your wacom pen – heavy use will see you wear one out in 6 months or 3 if you hold it with a death grip.
