I've bought literally dozens of gold, silver or white artist pens and none of them have worked properly. Ink generally dries out almost immediately, and the pen is useless afterwards. A white pen has NEVER worked. But these pens work PERFECTLY. I'm so happy with them and I would buy them again and again whenever I need them. Don't hesitate to buy these. They truly work like they are supposed to. Kudos to the the folks who manufacture these.
