Great printing, but does not withstand the water

disclaimer: I love sticker mule's products so much so I would never not use this company! This is a review for their new coasters. I did the promotion to get 10 for $1 recently because I was interested in trying them out to sell my artwork in little coaster sets. The printing was absolutely STUNNING, but when you use the coasters, the art work bubbles up on them due to the condensation from your drink. So I don't think I would ever buy these to SELL to a customer because they are not functional, and I think a customer would be upset that they paid for artwork on a coaster and it bubbled up and ruined the moment they used it. But I would certainly buy them for promotional products if it was something free I was giving out as an added bonus.
