I was under the impression that Kee manufactured it also, but in like with CapitolPaintball's post, the Valken paint is made in Asia......so the WPN paint would be coming out of Asia. Although I havent seen this stuff around in some time. Why are you so interested in it? There are plenty of balls out there that are easy to locate, good paint at a good price.
