I started with a base of Sally Hansen Insta-Dri - Lightening and stamped with Ulta3 - Black Satin (PRC version). I had trouble with this stamp. I think there is a problem with my BM-301 plate. I don't think the plate was etched deep enough, I've tried them all and they are all patchy. I tried for at least half an hour to get all the bees for this mani.
