## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for Active Toddlers – And Blippi Fans!
*by L***2 on May 27, 2025*

My son absolutely loves these cups! We mainly use them for milk, and they’ve been completely leak-proof—no drips at all. He’s super active and has dropped (and even thrown!) these cups multiple times, and they still work perfectly. They’re incredibly durable and easy to clean. The Blippi design is a huge bonus—my son gets so excited every time he uses them. Highly recommend for any parent looking for a reliable, toddler-proof cup with a fun design!

### ⭐⭐⭐⭐⭐ We love Zak!
*by D***P on May 3, 2025*

These are great for toddlers. They do not leak if tippoed over. If star liquid is cold, it will push up and leak very slightly from the straw top. I’ve found all cups do this so it’s not a deal breaker. I love that this comes with an insulated and non insulated option. The colors are vibrant and they have held up well with a wild toddler. I love that it comes with extra spout and straw.

### ⭐⭐⭐⭐⭐ Great cup!
*by A***R on July 24, 2025*

Absolutely love these cups! Doesn’t leak, easy to wash! My daughter loves the unicorn print!
