Leak proof and stylish stainless steel cup
[This review was collected as part of a promotion.] This stainless steel straw cup is the perfect size for my almost two year old. It’s completely leak proof with or without the lid on. The design is so cute and bright colored. I love that includes the rubber bumper know how much my daughter drops her cups. This will be great going into the warmer days to have stainless steel to cool her water nice and cold.

Love this flip top bottle!
[This review was collected as part of a promotion.] I really love how high quality this water bottle is. The handle on it is perfect especially for my 2 year old who is literally always dropping his water bottles. The straw takes a bit to pull out of but that is okay. I also like that there’s a rubber piece that goes on the bottom. This also keeps water so cold!

The cutest pattern and great materials
[This review was collected as part of a promotion.] I love this stainless steel water bottle for my 20 month old! I got this in the hot air balloon pattern which is SO cute! But they had so many great patterns available it was hard to choose! I love that it is made from stainless steel and can hold and keep liquids hot or cold! We mostly use it for water and milk but can definitely see it being fun to make hot chocolate in for a cold winter walk! Great investment as this will last for years!

Stainless Steel, Spill Proof? SOLD
[This review was collected as part of a promotion.] I am absolutely obsessed with the Grosmimi brand and these stainless steel Waterbottles are no exception. I LOVE the handles, which makes it super easy for my 17 month old to hold on to. I love the flip cap, especially to keep extra “things” out, since toddlers are notoriously not clean. The only thing is my toddler sometimes struggles with pushing the button to open the cap.

Perfect stainless steel toddler cup
[This review was collected as part of a promotion.] I'm so happy with this stainless steel cup for when my baby becomes a toddler. I like to avoid using plastic for health and environmental reasons so this cup is perfect. I'm always disappointed when a stainless steel cup has a plastic straw so I was so excited to see that this cup has a silicone straw. Not only is the cup durable but it is beautiful. I love that the design of this one, olive pistachio, is gender neutral. You can't tell in the pictures but in person the cup is shimmery and has a slight sparkle which I love.

High quality insulated water bottle
[This review was collected as part of a promotion.] This is a great, super high quality water bottle. I love that it is insulated and stainless steel. It keeps drinks cold or warm for 6 hours which is so helpful for being out and about with a baby who likes her milk! Very durable. I like the cover for the straw so it's less germy. The designs are also so cute!

Great stainless steel straw cup
[This review was collected as part of a promotion.] This is a good size stainless steel cup to use around the house or on the go. I can turn it upside down and it will not leak in the straw, only a tiny drop from the vent in the cap. The pattern options are cute and I like that it has handles so it’s easy for my toddler to hold. It fits in a water bottle pocket of my diaper bag as well.

Wow amazing bottle clean beauty
[This review was collected as part of a promotion.] This Korean design is highly praised for a reason. Beauty meets functionality. Quality meets design. Only stainless steel and silicone inner parts touching water. No plastic. Simple construction. No a thousand parts and crevices that can’t be cleaned. Super easy to open close for 1.5 yr old. Nothing else to ask for!

Great quality and design!
[This review was collected as part of a promotion.] Absolutely love this stainless steel straw cup. All the parts and pieces come apart and go together extremely easily for cleaning and use. I like that the inside has measurement lines and especially love that the handle is optional and rotates. That will be great for us as our child grows and their preferences change. The quality and craftsmanship is really great, and I love the subtle sparkle in the color. Personally the cost is a little high considering it really is just a water bottle. The fliptop was really easy for my child to maneuver.

Quality straw cup for transitioning from bottle
[This review was collected as part of a promotion.] This is a great heavy duty and well made straw cup that is easy for a baby or toddler to use. It has a helpful cap so that it doesn’t leak and a silicone bottom so it doesn’t get scratched or dented and stands up well. The stainless steel is non toxic which is important for little ones. My only complaint is that not all parts are dishwasher safe and it is a lot of pieces to clean.

Great for on the go, love the design
[This review was collected as part of a promotion.] My family is a big fan of Grosmimi straw cups, and we especially like this one for on the go use. My son finds it very easy to drink out of the straw, and since it is longer than the cup, it is easy even if there is not much milk left, though the straw doesn’t have a weight at the bottom so if he holds it upside down he cannot drink out of it.

Great company and unmatched quality
[This review was collected as part of a promotion.] I have a couple of Grosmimi products already, but got this for my daughter because not only is it so cute but I’ve been super impressed with the quality of this brand. I love that it is spill proof, which is a must with toddlers. The bottle is so fun I love the designs and had a hard time picking from all the options. The silicone is super high quality making me feel a lot more comfortable with providing it to my child to use.

Trendy cup for my little one!
[This review was collected as part of a promotion.] This cup is really pretty and attractive. My 2 year old came running as soon as she saw what I pulled out of the box and was asking to have the cup right away. We got the olive pattern and I love the color combination and the glittery background as well! It is definitely a pricey cup but it looks and feels very nice. I love that it’s stainless steel and not plastic. I like that it breaks down into so many parts for cleaning and the latch flip top lid is awesome for on-the-go. I think this will be a long lasting cup!

Grosmimi Stainless Steel Straw Cup
[This review was collected as part of a promotion.] A solid choice if you want a durable, insulated straw cup that toddlers can use on their own. It’s adorable, practical for everyday use, and worth it if you’re replacing regular plastic cups or want something that keeps drinks cool longer. It is on the pricier side compared to other toddler cups in the market.

Do they make these for adults?
[This review was collected as part of a promotion.] I was skeptical at first. Could this really be that much different from any other children’s cup? But the minute I opened the box I was sold. The quality is above and beyond. The design is very cute. The background is actually sparkly and smooth. This will help keep milk or other beverages cold with the stainless steel base feature. My one-year-old‘s eyes lit up when I put it on his tray. He loves to drink from it. I will say the button is a little harder than he can push at the moment, but I would rather that than too easy. Very impressed with this little sippy!

Beautifully designed and practical
[This review was collected as part of a promotion.] This is a really cute water bottle and feels really well made. I love the shimmer of the outside and the dainty cherries are darling. I don’t love that it’s hand wash only but it’s worth it to have such a cute water bottle for my little girl. The handles are super easy to grasp and the straw is not as directly to drink from as some other cups we’ve tried. Love this!

Great quality stainless steel bottle
[This review was collected as part of a promotion.] We already have this same bottle in the plastic version so when I saw stainless steel was available I had to buy it. I always feel better about my toddlers drinking from stainless steel rather than plastic. This bottle is super sturdy and it comes with a silicone boott to protect it from dents. The design has a subtle glitter sheen and it makes it so pretty! Wide age range as both my 19 month old and 4 year old can use it.

Well made, cute design, useful
[This review was collected as part of a promotion.] This is the second cup we have bought from this company and they are extremely well made and durable, and has a cute design. There is an option to use it as a straw cup but you can also take the straw out and tip it back like a sippy cup which will be helpful for my 8 month old as she transitions. Great product.

Excellent quality stainless steel straw cup
[This review was collected as part of a promotion.] I am very picky about the sippy cups and bottles that my kids used and this is such a good find! Really excellent quality. Love the stainless steel and overall design. No pesky seals that trap mold and it’s easy to disassemble and run through the dishwasher. The silicone sippy straw and top seal everything so no leaks. Love the bottom bumper too. The teddy bear design is super cute! My kids love this from my 5 year old, my two year old and my baby that’s learning to drink from cups for the first time.

Stainless cup for the win
[This review was collected as part of a promotion.] There are so many things to love about this stainless bottle! I love the teddy bear pattern but the others were super cute too. I love the fact that it’s stainless and it has removable handles for little ones to grasp if needed. ! It also has a silicone sleeve that fits on the bottom to protect it from denting.
