Review: A Must buy for your toddler…. - This tumbler is durable and cute. Totally spill proof and easy to clean. A great travel tumbler. Great for the summer with keeping all cold…
Review: Instant favorite the moment she saw the princesses 👑 - This was such a hit with our daughter! She was immediately excited when she saw all the princesses around the cup, and now she wants to use it for everything—water, milk, even juice. The design is super cute and wraps all the way around, which she loves because she can spin it and point out her favorite princesses. The cup itself feels really well made. It’s sturdy enough to survive drops, keeps drinks cold for a long time, and has been completely leak-proof for us so far (even when it gets tossed in a bag or knocked over). The size is perfect for a toddler—easy for little hands to hold but still holds enough to get through outings or bedtime. One small downside: the straw has a few pieces, so it takes a bit more time to clean compared to simpler cups. Not a dealbreaker at all, just something to be aware of. Overall, this is a great gift and we’d absolutely buy it again—especially for any princess-loving kid! 👑✨

### ⭐⭐⭐⭐⭐ Just what I have been looking for!
*by H***N on October 8, 2025*

I have spent a lot of time trying to find a cup that doesn’t spill that my toddler can use on his own. This one is perfect! The straw is a little bit tough to suck from, but he figured it out so fast and it actually slows him down so he doesn’t drink too quickly and choke. The cup is insulated and keeps the drink cold. I put ice in it and it lasts for hours. The straw comes out and the silicone straw and piece that prevents leakage also comes out which makes this cup so incredibly easy to clean. There aren’t any places where mold can grow and hide. I did notice a few drips would come from around the silicone on the top if the cup had been tossed around, but not enough to complain about or take away a star. The design is so cute and so far hasn’t faded or chipped after washing. It says dishwasher safe, but I have washed it by hand. 10/10 would recommend this cup and I will be buying more!
