Nope, I've never even heard of it until I just Googled it. I cut up a brown paper sack into small circles. It works better than anything else that I have tried. I do know several places to find those if you don't have any luck.
I've searched for a couple of years for it. I finally found some sources but the minimum order is well into 4 figures. Doing the math I figured out it was cheaper to buy the cups from TJ's or build my own using Tyvek.
