Review Content Great Glasses Really glad I purchased these glasses. Great quality, keeps temperature longer than any other beer glasses I have owned. Thick, but can see through very well. I love it!! The day the mugs arrived I had a good size gathering at home. I put the mugs in the freezer and an hour later started using them! They where a sensation! Seems I should gave bought more! A very nice product! Ive always had a problem keeping my drinks nice and cool. Specially my beer! Now the beer remains cool and my friends love it, many of them said they will be buying some for their use!
