I love my Tervis Tumbler.
One of my 20 in 2012 was to drink water every day...and this cup allows me to do not only that, but I can drink anything hot or cold out of it. It doesn't "sweat" like other cups. It fits in the cupholder in the car. It can be used with a lid and a straw or a travel coffee lid. It's virtually unbreakable and microwave & dishwasher safe.
But the best part is that you can customize it to your favorite sports team, your name, or just a cool pattern.
I, of course, have a Virginia Tech one.
And while writing this post I have come across a NEW Tervis water bottle design that I may have to buy...hmm.
Happy Cinco de Mayo and Derby Day!
P.S. You can use your Tervis for margaritas too!
