We have been noticing these tumblers offered by many different stores lately, and decided to jump on the bandwagon and order some. We decided on these because,hey, the color is a beautiful copper color and it just looks classy! Lol. When they arrived ,we put them to use right away. They work better than expected. Another great feature is the sealing ring under the lid. If you.happen to knock it over, it definitely helps in preventing spills. This is a very good purchase and we will be purchasing more soon!
