Made by U.S. Acrylic Inc - Made in the USA - thick plastic tumblers. There are 8 of them, all dark blue in color. The outsides of the tumblers have a light texture for easy grip, the insides are smooth. Each tumbler is about 6" tall, the opening is 3.5", the base is 2.5".
On the bottom of the tumblers has the impression into the glass that says on some "Made in the USA" on others it says "Made in the USA " and U.S. Acrylic Inc.
All of these are intact with light scuffing from use. No breaks, cracks or repairs. They are heavier duty than say Tupperware tumblers. I'd say they are perfect for an outdoor beer glass, lemonade or Iced Tea by the pool or outdoors at a picnic.
