Mainstays - Blue Square Plastic Tumbler, 18-Ounce

from Selene

This is a perfect cup for kids! I love the color and it's really sturdy, dishwasher safe. I have actually gone out and bought a few more of these for the summer time now that we have more kids over and more cups being used.

I love this tumbler first because of the color and that it's dishwasher and microwave safe. I especially love that it's BPA-free. These are great for the price and durable that you can use them over and over and for indoor and outdoor use!!! Just great all around so go get some.

Great cup, this is the second one we have. My daughter uses this one and the green one on a daily basis. Well made and no complaints. I have used before with some juice and have no complaints. The corners have a unique shape that make drinking from them enjoyable.

This Mainstay cup is a smaller cup, average size. It is a heavier, more sturdy plastic cup with a squared opening on top. It washes well and is dishwasher safe. Great for smaller kids and easy to hold.

I like this plastic tumbler, perfect size for my grandson when he comes to visit. I don't have to worry about him breaking it, I would not use glass just yet with him. Also, his favorite color is blue so he loves it and always looks for it when he is having something to drink. Very durable too!
