In 2017, we still had ours from 1991, but I didn't trust the mylar coating. I thought it might crumble if I so much as breathed on it. So, I ordered new ones from Amazon. The came in a box that was about three feet long. One little packet rattling around inside with the cardboard glasses in it. I think somebody punched the wrong code for shipping them, and the shipping department just followed orders. Was ridiculous.
