Kids 10oz Stainless Steel Mason Jars + Sleeves + Lids | 4pk | Toddlers | Silicone Sleeves | Straws with Stoppers | Food Storage | Spill Resistant | Dishwasher Safe | Perfect for Smoothies

These are absolutely perfect cups. I love how they come in packs of 4, it’s much needed for my toddler! The straws don’t fall out, the silicone cover protects from dents and looks cute, and the size is easy for her to hold (though she likes picking them up by the straw). They completely come apart for a full, easy cleaning—no hidden cracks for mold to hide! The keywords in the title fit better than what the description says—these are spill resistant, definitely not leak proof. They can be knocked over and picked up with just a few drops spilled. But if they were turned upside down, you’re going to have a lot spill out. They are definitely not for the crib. Overall I love these and will be grabbing more colors in the future.

Great snack cups or water cups. Not leakproof if you are looking for that. Washes great in the dishwasher top rack.

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.

Dishwasher safe + Not spill proof - Overall good quality

These are great for young and old toddlers. My one year-old has dropped it on the ground and because of the silicone lining it hasn’t broken. Very easy to clean. The only thing to note is if it’s dumped upside down, milk will spill through the straw. If your toddler is on the younger side of 1, it was heavy for him to pick up.

The Elk and Friends 10oz Stainless Steel Kids & Toddler Drinking Cups have quickly become a favorite in our household. I have purchased 2 sets already as my sister loved them as well and I shared a couple of them with her. The 10oz size is perfect for toddlers and young kids and easy for little hands to hold without being too heavy. The stainless steel construction feels durable and high-quality, and the colorful silicone sleeves add a fun touch while giving kids a better grip. They’ve already survived a few drops without any dents or scratches, which is a win in my book. The spill-resistant lids and soft silicone straws are what really set these cups apart. The lids fit securely, which helps keep drinks from leaking during meals. The silicone straws are gentle on kids’ mouths and make these great for everything from water to smoothies. It’s clear the design was made with young children in mind - both safe and functional. Another thing I love is the versatility. These aren’t just drinking cups; they double as small storage jars, which is surprisingly useful. Whether it’s snacks, leftovers, or little items you want to keep sealed, the airtight lids do a great job. And since every piece is dishwasher-safe, cleanup is simple and quick — something every parent can appreciate. The materials are also a big plus. The reusable stainless steel and silicone are free from harmful chemicals like BPA, making them a safe and eco-friendly option. They feel like they’ll last for years, reducing the need to constantly replace kids’ cups as they wear out. Overall, the cups are a fantastic choice for families. They’re sturdy, thoughtfully designed, easy to clean, and genuinely helpful in cutting down on spills. The bright sleeves make them fun for kids, while the functionality and durability make them a favorite for parents. I highly recommend this.

We have been trying to reduce our plastic use and so I was excited to see these cups for an affordable price. The build quality is nice, but they are NOT leakproof. I thought the lids were going to be a form of silicone too, they are plastic, and the silicone straw doesn't seal where it enters the cup. Kind of a bummer because my toddler takes his water cup to bed and can't do that with these. He also dropped it from his carseat and chocolate milk got ALL over the back of my car. Decent cup, but if you need something truly leakproof, I'd search elsewhere.

I recently purchased this cup set for my toddler and overall, I’m quite happy with it. One of the standout features is that it has multiple uses from cups to snack containers. They also have a wide variety of colors it comes in—there’s something to match every personality. The material feels high-quality and durable, which is a big plus. It also cleans easily, whether you're hand-washing or using a dishwasher, which makes it super convenient for everyday use. However, one downside is that it's not spill-resistant. If you're using for a little one who tends to throw or drop their drink, this might not be the best option. But if you mostly use it for snacks or for older children, it works just fine. In summary, it's a great-looking, well-made cup that's easy to maintain—just be cautious if your child is prone to spills.

Me gusta su tamaño ...ya contaba con el tamaño menor y siempre me gusta su calidad

Sehr hochwertig und praktich für Kinder, damit sie zuhause trinken nicht vergessen, igal beim Spielen oder malen ect.

LOVE these! So cute, easy to clean and my toddler enjoys milk, juice, smoothies from these! Even my 10y/o niece loves them

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

Love the colours, and how versatile it has cover and straw covers with reusable straws. Would recommend!
