I picked up 100 ea.16x + & - silver top from Shop4Tech about a month ago. the + are pristine but the - have a few nicks and what appears to be a few specs of dust imbedded in the dye because you can't get rid of them with a blast of gas duster but even still most of them burn well. I hope your printables are in nice condition, I have gotten TY printable with spots around the dye side outer edges from these guys before.
