Oh gosh, I had no idea that anybody ever looked at this old thing! D:

Anyway, Prismacolor marker ink is technically permanent and waterproof, but certainly not archival quality. It is alcohol-based, meaning that it won't wash off with simple water, but it will fade quickly when exposed to sun, and will absolutely be washed away by exposure to anything of similar solvent quality (rubbing alcohol, for instance). So it should not be invasive when exposed to other garments in the wash, and I doubt the color will last long on fabric anyway.

I hope that helps. Sorry for the late reply... Seriously, I had no idea that this old thing was still being found and used by people. ^^;
