Review: Muy buen tamaño, no derrama nada, muy fácil de limpiar, no tiene tantas tapitas incómodas donde a veces se les guarda moho, volveré a comprar más vasos de este tipo, a mi hijo le fascina, el popote es ancho por dentro y por fuera es muy suave
Review: The indestructible Bluey cup that survived teething and toddler teething! My 20 month-old is deep in the “everything hurts my gums” teething phase and this is the ONLY cup she’ll use right now. The silicone straw is super soft and flexible; she chews on it like a pacifier and it just bounces back, no cracks or tears after weeks of use. She’s dropped it off the high chair approximately 8,000 times (hardwood floors, tile, concrete patio, you name it) and it has never once leaked or cracked, or even popped open. I’ve stopped flinching when it hits the ground. It also holds 10 oz, which means I’m not refilling milk every 12 minutes like with her smaller cups. Bonus: the Bluey design makes her light up every time she sees it. Dishwasher-safe, drop-proof, chew-proof, and actually spill-proof. I’m buying two more so we’re never without a clean one. If you have a teething toddler who treats cups like frisbees, this is your holy grail. 🦷💙

## Questions & Answers

**Q: Does the Kelso prevent spills when the tumbler is tipped over?**
A: Yes, and you don't need to remember to close the lid! The Kelso tumbler has a valve in the spout, which lets water flow freely when kids are drinking, but stops spills if the tumbler is tipped over.

**Q: Is the tumbler easy to clean?**
A: Yes, both the spout on top of the lid and the inner straw underneath the lid are removable to make cleaning easy, and the parts are all dishwasher safe.

**Q: How old should my child be to use the Kelso tumbler?**
A: We recommend this tumbler for kids age 3 and up.

**Q: What kind of drinks can go in the Kelso tumbler?**
A: The Kelso tumbler is perfect for everyday cold beverages like water, milk, or juice. Thick smoothies are a little more difficult to drink with the valve, while carbonated drinks can build pressure and push liquid up through the straw.

**Q: Can I travel with the Kelso?**
A: The Kelso tumbler fits in most car and stroller cup holders for on the go convenience. We don't recommend putting the Kelso tumbler in a bag, as pressing on the soft spout can open the valve and allow drinks to flow out.
