Navy Dish Set/Awesome

Thanks for having navy tumblers /dishes. I finally was able to get all the pieces to this set because Walmart sold them separately. I had been wanting Navy dish set for over a year and half. I was also blessed to get them for such a low price for each item. They wash up well. Thanks Walmart!!!

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.
