Shatter/kid proof, camping/household/bbq worthy

I love these Mainstays 18 oz tumblers, I have the blue and gray. With summer break coming closer these tumbler are virtually kid and outdoor proof, which is where most of the drink ware ends up, outdoors with kids.Building a collection for the kids newly renovated pop-up camper, along with mainstays blue and gray plates. Hopefully reduce disposable tableware this season, our planet is so worth it. Yay Mainstays and Walmart!!

Pretty nice cup

I like the cup a lot if you like it's a good cup to mix your stuff in with a little bit of pop and a little bit of whatever you like and a little bit of juice. The size is nice so you can add whatever ice you need to add as well. I just like how wide the opening is as well.

Tumblers are great

These tumblers are durable and are the perfect size for my grandkids to drink from. They are nice looking and the color matches well with the dishes I have. I am happy with my purchase.
