Review on ☕ Enhance Your Coffee Experience with Glass Jumbo Handle Coffee Drinking by Matthew Watkins

I have an order for 60 glass mugs to be custom made for teachers. I almost cried the first two glasses because the vinyl DOESN'T STICK! I googled my problem and read that some glasses are made with film (which I already knew but alcohol helps) and suggested using acetone. Luckily it worked! A paper towel dampened with acetone to clean the surface, wait a few seconds for it to dry, apply the vinyl and remove the film that leaves nothing! Wow! I had to write a review immediately in case someone else needed it. I don't use mugs to be honest, so I can't help you on firmness or heat resistance, sorry.
