Tiki Tervis Tumbler keeps summer drinks cold

Although you may have never heard of them, Tervis Tumbler makes fantastic insulated cups that really do keep drinks colder in the summertime without ice. The company's schtick is that they place colorful patches between the layers of clear insulation to decorate the glasses. I used to live about 30 minutes from their small manufacturing facility in Florida, and local lore had it that they would put anything between the layers, including dead anatoles, those little lizards that run around the sunshine state, for walk-in customers.
Personally, I'd much rather opt for this tiki design, which features:
* 24-ounce capacity
* High-grade polymer material
* high quality embroidered patch
* Dishwaser safe, Microwave safe and Freezer safe
* Unconditional lifetime guarantee
$31 for a set of two
