Great kids cup that is leak proof
I ordered this for my two year old. He can drink from regular cups but us in the toddler stage of enjoying dumping food and drinks. I can't tell you how many drinks we have cleaned up recently. This cup is stainless steel. It's easy to clean given the wide spout. I am also very glad that it is spill proof. This would be a great present

Great quality and cute designs
My four year old has a different tumbler from this brand and she loves it so much. I was excited to see the same brand offered a sippy straw version that my almost-two-year old can use. I really dislike plastic sippy cups so this stainless steel version is SO great to have. I feel safe having my toddler drink out of this and not having to worry about microplastics, plus the pattern is so adorable. It’s sustainable and the quality is definitely worth the price tag.

Perfect stainless steel cup for toddler
I was so excited for this cup because I try my best to avoid plastic. I love that this cup is made of stainless steel. Also, I was so happy to find out th straw is made out of silicone. Sometimes a metal cup can come with a plastic straw which is always disappointing to me. This cup is so sturdy, easy to clean, and beautiful.

Grosmimi stainless steel straw cup
I love this cup!! The color and design are so cute. The straw makes it easy for my child to drink from and easy to keep clean! It is leak proof and because it is stainless steel keeps drinks colder for longer!! I also love that it has handles on the side so my child can hold both handles while drinking. The only thing that I would change would be buying this in a larger size that holds more water for older children!

Perfect Little Cup for Little Learners
I absolutely LOVE Grosmimi products. They are stainless steel, so your kids aren’t drinking dishwasher detergent aftertaste, durable, and so easy to clean. The four parts of this cup come apart easily to clean and are dishwasher safe! I love that the straw has an easy to cover cap to keep the gunk out.

Grosmimi Stainless Steel Straw Cup
Bought this for my little one and it's been really easy to use. The handles are perfect for small hands, and the straw opens and closes smoothly without leaking. I like that it's stainless steel, so it feels sturdy and keeps drinks cool longer. The design is cute and looks good in person. Overall, a nice everyday cup that feels well made.

Loving this new cup for our grandson
We gave this cup to our grandson for his first birthday. He is still getting the hang of drinking out of the straw and it is cute to watch him. According to the package, this is made for 12+ months. I love that this is stainless steel. That is my favorite thing to drink out of. I like it much better than plastic. And it is nice that they are measuring lines on the inside of the cup.

Wonderful simple clean bottle
Love this bottle— only stainless steel and silicone touching water. No plastic and concerns. No thousand pieces and crevices that can’t be cleaned. After molded plastic bottles don’t want that no more. Easy to use and pretty. Korean design nailed it. Baby loves drinking water with it. Best bottle we’ve had!

Cutest little bottle, easy for babies to use
My 13 month old daughter uses this cup easily. It is super high quality with stainless steel interior keeping her milk cold for longer. She has dropped it a number of times and it's not broken or scratched at all so super durable. It was hard to choose from all the cute patterns but we got olives and it's adorable. Love the cap that keeps germs away too.

Absolutely adorable and really nice straw cup
This is a really nice high quality stainless steel straw cup. One great feature is that it has the lid that clicks shut on top also. I also love that it has the handles on it for better grip of the cup by your little one as they are learning to drink from something other than a bottle. The stainless steel keeps water at a colder temperature so you don’t have to worry when taking it filled with water in the summer. It doesn’t leak which is a huge plus for me and it has measurements inside so you know how much your little one is actually consuming.

Grosmimi stainless steel flip top straw cup
This is the second Grosmimi Stainless steel fliptop straw cup I have purchased by the same brand and I am completely satisfied. Initially, the price was above what I would typically pay for children’s cup however after receiving the product and realizing what high-quality stainless steel was utilized and other top notch material materials used to make this cup are absolutely incredible. I love that the stainless steel will keep and maintain the temperature of whatever liquid is put in for up to six hours due to the vacuum seal of the stainless steel. I truly appreciate there are different phases and they are spot on with each phase. I also enjoy this 6 ounce versus the larger 10 ounce. The way these cups clean up and keep is impeccable. And the designs and patterns available are absolutely adorable! This guy air balloons are my favorite in creamy blue. What a great value. I will purchase from this brand for life!

Cute Design and Easy to Use
I have a lot of nieces and nephews, so I like to make sure I have cups at home that they can use. It's always nice to have an extra sippy cup to pull out, especially one that does not spill easily and can be used for a variety of ages. This is nice quality, and very cute. I like that it has handles, and a flip top to keep it closed. It also has a nice little silicone sleeve that slips onto the bottom to help it not be so noisy and also protect the table/floor/wherever the toddler drops it.

In love with this brand of sippy cups
This is such a great product. I bought this for my 11 month old baby. First of all I love that these sippy cups are stainless steel so it’s no harmful plastics for my baby. The pattern is so cute and simple. The straw is made of silicone and soft on my baby’s mouth. He is able to sip this up easily. I love that the lid closes to keep bacteria off of the straw. The handles are perfect for his tiny hands and it’s not too heavy. He does throw it often and it hasn’t broken! There is even a rubber grip on the bottom to keep it in place. Very great quality.

Cute straw cup for young toddler
I love the print options of these straw cups and that they have handles for my young toddler to hold. They don’t leak when you tip them upside down so they are perfect training cup. I like that they are stainless steel and there’s not too many pieces to clean. This is the smaller size so I use it for my younger child rather than my older kid.

The perfect size bottle!
We are in the process of transitioning from baby bottle to a sippy cup and this is the perfect size for my 1.5 year old! Also the design is so cute and he loves it. I do have the bigger size in this bottle but I think it is too heavy for my son and he prefers this size way more. I love that it is leak proof and the button on the bottle is easy to push for him. Also the cup is metal so his water and milk stay cold longer!

Adorable and nice quality kids water bottle
I am new to this brand, but love the water bottle! The flip cup design is really nice. Babies can learn to use a straw, but bigger kids can use it too. The 6oz size is perfect for toddlers and the optional handle is great too. Even babies can easily hold it whereas a lot of stainless steel options don’t have that. I love that it’s easy to clean and doesn’t have weird seals that will gather mold. Super cute too!

Good durable cup for a young one
This cup has been a great everyday option for my 1.5‑year‑old daughter. The two small side handles make it easy for her to hold independently, and the flip-top lid helps keep the straw clean when we are on the go. The straw design gives a good flow without too many spills, which is helpful as she’s still learning. The body feels sturdy, and the cherry pattern looks very cute and girly on the counter. Overall, it feels durable, easy to clean, and toddler-friendly, so it has quickly become one of our most-used cups.

Cute cup, works great for toddler
This is a great portable cup for a toddler. We use it for my son and niece who range in age from 14 to 21 months. Both find it easy to push the button to open the lid. As a parent it’s super easy to clean, I put it in the dishwasher! We like the small size of it for quick trips out. The design is so cute too!

Great transition cup for one year olds
I got this cup in the peach pattern which is perfect for my little girl! Right now her brother is using the cup since she isn’t quite old enough but I got them each their own patterns. I love that it has an attached lid so you don’t lose it. My son loves clicking the button to open it- he is 20 months and has no problem doing it. I also love that it has handles so he can easily carry it wherever he goes!

Great bottle, flawed Handles
This is such a cute little water bottle. My twenty month old loves it! My only complaint is that the handle is very loose and swivels very easily. My daughter has some motor delays and the handle sometimes swivels when she reaches for it making it harder to grab. I do however love the silicon gripper for the bottom to help it from sliding around or denting if dropped. Overall I would recommend it but the price point seems a little high for a kids water bottle. I received reimbursement for the product in exchange for an honest review.
