A great white pen! I have tried many others--Sakura, Signo, etc. And this is the only one that I can get to work for me. Since it is a marker, it always works for me and you don't have to worry about the gel from other pens which doesn't work for me at all. The only thing is that it goes on clear right away, but as it dries it appears and I absolutely love it.
When I first started using this on a black piece of card stock, it didn't flow well, but after a couple of words on scratch paper, it started to flow and covered well. It looks like chalk which is the look I was going for. I recommend it.
