I love these cups!
These cups are versatile, easy to clean, easy for children to hold without slipping and they hold 18 oz. Great price for a well-made product. I bought 10 to replace some of our older cups. Definitely recommend, and I'll probably buy more in a different color!

Cost-effective
We were spending quite a bit of money monthly for styrofoam cups. We use these for our clients to keep and re-use. It saves us a lot of money, plus is better for the environment. We have the clients use an acrylic/oil based marker and put their name on them. The clients can be very creative. They are perfect size for a cup of coffee as well as a cold drink. Price-wise they pay for themselves. They are sturdy and don't tip over as easy as the other cups. Very pleased.

I buy these for a specific purpose, not for drinking. So, for what I use them for, these are the perfect size. I'm not too fussy on the color or the fact that they don't have a lid. For what they are, and for the cost, these are perfect.
