OMG this makes my life so much easier! I was using mirror covered with a sheet from another manufacturer.,, their item worked brilliantly but it stuck TOO well and getting large flat items off the surface was a PITA… now I get the same ‘stick,’ a smoother finish, and now I don’t have to break my fingers and tools to get my prints off… also, magnetic base and sheet combined are lighter so it’s less wear and tear on my machine and less ringing in my prints with the 310x310 size… SO glad I found this!!
