The glasses were great! The ice molds were a let down. Only one of them held water and the other is essentially useless because it doesn't hold the seal and water seeps out only making 1/2 and ice ball. Pretty disappointed

After having this on my lips for 20 minutes they started tingling in a way that reminded me of an old plumbing lip gloss I had long ago. My lips definitely felt more swollen afterward, however I suspect the only one who could notice a difference was me.

Ex Input:
Very Pretty Colors! But; I bought these as I thought they were very pretty and not being crafty I thought they would be a nice touch on the baskets this year. I opened the amazon bag and at first I thought they were the labels. Nope, flat ribbon no instructions not a clue on how to assemble these things. Very disappointed.
