No, not much info. at all. They are a bit cheaper than most. I tried their 25 micron rosin bags and, so far, I'm not hugely impressed with them. I've only had a couple of nug and kief runs with them. But, I'v seen blowouts under normal time, temp., and pressure (compared to Rosin Rev. and Rosin Tech). I'll let you know about the mold.
Good to know the quality's there. Thanks. I'm using a Rosin Revolution pre-press and it's also tight. I have to turn it upside down and bang it against an arbor plate to get the sleeve to slide off (esp. when pre-pressing kief). I don't mind doing that, since it produces really nice little bricks.
