Elk and Friends Kids 10oz Stainless Steel Mason Jars + Sleeves + Lids | 4pk

We’ve been using these for a while and they have been great! They are extremely durable and easy to wash. I love that they aren’t plastic. They do spill when tipped though so be aware of that.

Good for a toddler. Happy they are not plastic. Wash well. Of course may drip a little bit if you shake them upside down too much but it's a straw. But have not had many spills at all. Durable, perfect size for little hands. Not heavy, cute colors.

Edit update (Feb 2026): Updating this about the dishwasher friendliness - we no longer put them in the dishwasher because the stainless steel and silicone straws were retaining the taste of the detergent/soap. So we hand wash them now and make sure to rinse very well. Otherwise they have held up! Original review (Sept 2025): These are super cute and my 4 y/o daughter loves them! So far they are sealing tightly and have not spilled when taking a tumble. My one critique after filling them with ice water a few times - the quality of the stainless steel is less than expected. The cups sweat / form condensation on the outside and don't keep the drinks cold like a water bottle - I figured stainless steel would keep drinks cold and prevent the sweating but I guess they are not that kind of construction. Easy to throw in the dishwasher. Love how these can go from use on the house to the car seat in a pinch and not worry about spilling/glass breaking (been trying glass too to de-plastic). Love that they are not plastic (though the tops are, that's fine) as we try to eliminate plastics from our kitchen and dining wares.

Favorite kid cup. It is easy to clean and assemble. The dishwasher friendly nature makes it a 5/5 for me!

Probably not for toddlers but I use these for smoothies for my 5 years old. They can leak from the straw if left on their side. I really like them because it’s easy to clean and small. The lid is plastic but most stainless cups have plastic lids. The plastic is thick so hopefully it holds up.

These are great cups! Love that they can be either drink or snack holders. Very durable! Bought them for my 3 year old and she does great with them. They aren’t spill resistant but don’t leak as bad as other cups with straws. Will buy more to replace our other cups and will give them as gifts to new moms!

Use these for my toddlers smoothies, love them. Great grippies in the outside and the stainless keeps everything cool. Does leak around the straw so not leakproof but otherwise my baby doesn't have any issues using it!

I really wanted to like these cups because they look nice and my toddler likes the colors. But we can't put anything in it but water, and even that ends up everywhere. I'd say I'd just put them away until she is older, but they're small for a kids cup. For the price I was expecting more.

No me encantaron porque no son prueba ant derrame en realidad son para niños que ya dominan perfecto el uso de un vaso pues pueden tener accidentes. Los colores son bellos y la composición está bien pero no lo recomendaría para niños menores de tres o cuatro años

My grandchild loves them!

very cute and colourful but not many uses before mold formed under the seal. disappointed as these weren't cheap

These things leak like crazy! I would NOT purchase these again and I do NOT recommend them.

Super cute. Work great for snacks (even comes with snack lid), but they leak very easily when used for drinks. Not great for toddlers as mine just flip it over and dump all the liquid out. Would be good for older kids though.
