I never saw it mentioned on the web, but it has a terrible smell like sharpie marker. It dries super fast in the package, even keeping it in a ziplock baggie. Other than that .it was ok but Plus clay is much better in my opinion, and similar in all the good ways.
I use this tape to hold the Mylar on the drafting table. It's a very good tape! It releases without leaving residue, and it is thin enough to let the rule slide on top. The tape doesn't break while unrolling, unlike many others.
I highly recommend it.
