Spill proof cups

These spill proof cups are adorable. My grandaughter takes them everywhere. Im always struggling to find spill proof cups that are actually spill proof. These pass the test. . They’re very strong and sturdy, and keep drinks cold for about twelve hours. They make great gifts.

Cute design

He's obsessed with this tumbler! It keeps his drinks cold for hours (and hot when need it), and it doesn’t sweat or leak. Super sturdy and perfect for on-the-go—whether at the park , or just relaxing at home. The design is cute, and it fits perfectly in a car cup holder. She use it every single day!

Flexy steaw winner

My whole family love these! I really love them for my 1 year old he thinks he is so big. So i love that the straw is flexible on top so it doesnt hurt him. Really love that no matter what age is using it they arent leaking water all over when its forgotten. They have withstood being dropped so many times! Just get them!

Princess 2 pk Tumblers

This tumblers are so adorable. The color, size and the size of the handle are perfect for small hands. The design are so cute , all the Princesses . Love the color too , peach and purple. But most of all it’s leak proof. So you don’t need to worry in the car seats or strollers .
