I loved this mat since I got it a month ago [SEP] I loved this mat since I got it a month ago, but now as of tonight I'm sad. It does say that 99.5% of polish doesn't stain it ...well as you can see I have stained it with metallic polish from opi....now that part of my mat is ruined, I cant use it for stamping in those places because the clear polish that I put down there comes up stained also...soooo sad.  But, I will say that the polish dries real nice and it peels right off withy out ripping or tearing your decal.Its not flimsy at all and its fairly big so you have a good amount of work surface.
