Love this product! My illustrations, photography and graphics look great when printed on these.

Better than expected

I was ready to give these coasters one star. When I opened the package, it seemed like the surface was all scratched up. I did a test run on one, and the sublimation paper stuck to the surface. ( I am using a Cricut Easypress 2 - 400 for 60 seconds).
I managed to get the paper off, which was now glossy.
That is when I realized there was a clear protective sticker on the coaster's front. OMG, I felt stupid.
On the second try, after taking the protective sticker off, my printing was perfect!
I will be repurchasing these.
