Elk and Friends 10oz Stainless Steel Kids + Toddler Drinking Cups | The Original Mason Jars with Lids + Sleeves + Straws | Smoothie Cups | Spill Resistant | Dishwasher Safe | 4 Pack

Great durable cup. The seal is decent from lid to cup, but it is not spill proof (it can spill out of the straw hole).

Nice first cups for my son! I love that they’re stainless steel and silicone because I hate giving my baby plastic if I can help it.These are awesome because they have a convertible lid so you can choose to use a straw or not. Also fun colors!

Love these cups! Both sizes are great. Used the small size until 5 and now use both. Not spill proof fyi but perfect for around the house. Mix and match.

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.

I’m beyond happy with the Elk and Friends Stainless Steel Cups! The mason jar design is clutch, and the stainless steel construction makes them durable and versatile—not just great for drinks but also for storage. My son drinks from them with ease and enjoys using them, especially with the silicone sleeves and straws with stoppers. It’s a well-thought-out design that works perfectly for toddlers and kids. Highly recommend!

We love these cups. They are easy to drink from. The cap seals well. The bumper cushions the blow when my son throws it off his high chair. My only complaint is that is leaks out of the straw and the hole for the straw depending on the angle it lands in. Otherwise, good quality and perfect for daily use in the house.

These are definitely NOT spill- proof. I think it does say that in the description, but it's worth mentioning again. They only include O-rings for four of the 8 cup tops which seems silly. Why not include the rings for all the tops so you can quickly switch from the solid top to the straw top? I love the stainless steel cups because they are easy to clean. The size is great and the silicone makes them grippy. I wanted to really love these - unfortunately I only LIKE them. I'm keeping them for dry snacks and fruit. I may never use the straw tops again. They fit perfectly in the car seat cup holders.

These leak if you turn them upside down. They also leak a little out the top anyways. So it could use some work on the design there. But otherwise, the cups are made to last, are super cute, and easy to clean.
