These are the perfect solution for my children's small hands that aren't plastic and that won't break like glass! I highly recommend these and my kids like them too!

They are the perfect size and feel high quality.

Love these cups. They are exactly what I was looking for for my 3 1/2 yr old. The size is perfect, they go in the dishwasher fine, and the price is reasonable. I'm sure these will last for years. I bought 3, and plan to buy more in the future.

We love these cups and will be buying more. They stay clean, wash well in the dishwasher, and aren't as tippy as a regular plastic cup.

We bought 8 of these tumblers for our 8 grandchildren. We had previously bought molded plastic cups with each of their names on them - two of the handles broke off when they dropped them, you could see mold starting to develop between the layers of plastic, and they only have certain names that can be molded (two of ours weren't on the list).

These tumblers are going in each grandchild's Christmas stocking so we haven't yet used them but they look great. I had each engraved with a grandchild's name on the front and they look adorable. And as the engraver said this morning when I picked them up, "you can't go wrong with stainless steel".

The only feature that prevents a 5-star rating is that I wish the lip of the cups was a little more rounded. It has an edge similar to a butter knife, so not sharp but something noticeable. That said, my 2-year old niece had no problem with them and they're versatile and easy to use. We're very happy!

Great stainless steel cup. Inert and safe! Edge is smoothed, but a little sharper than I expected, but not like it would cut or anything. I wish it came with a top though so my kid could use it outside in summer with a straw with no spilling. I'm really being picky now. Overall, this is an awesome cup and I'll be ordering more when my budget allows.

Review by Natalie on 6/17

I love these cups. My kids love them & my husband loves them when we go camping. No more hot chocolate in plastic! They won't break, & my kids have droped them- no dents yet! Great for children to grab their own cups without the worry of breaking.

Review by Sara Kreps on 5/29

Great quality cups. Love how they stack tightly together and don't take up much space.

Review by toto on 4/8

No question, these are good quality and will last for decades. I'm very happy with them. It's difficult to find 8oz stainless tumblers, and these fit the bill.
