Shawn, pretty cool pen, "the wonderful thing about tiggers is tiggers is wonderful things"
I know it's corny, and not tiger but I just couldn't help my self!!
I don't know if it will attack the acrylic. I don't see why it would though.
I was given a tube of the stuff - somebody on FPN bought some to play with, didn't know how to apply it, and then sold it. The person who bought it sent it to me w/o telling me they had even bought it. Very nice little surprise.
There's a Japanese website you can buy it from no problem. I think about $65-80 shipped.
