I have seen similar, but it usually is more closely defined: "Archival Inks that will last for 500 years!!"

Well, maybe .. but they do not mention the paper, or the life of the inks when apllied to, and therefore combined with, the paper.

I could imagine - actual document life ~ 2 months... but, "It isn't the ink's fault - it was the paper..."

They continue ..."GUARANTEED - Or Your Money Back..." but that applies only to the ink ... and who is going to collect after a 499 year failure?
