Meet the Zak Designs Kelso 15 oz Tumbler Set

The Kelso line brings a reliable, kid-friendly hydration companion to your home or on the go. Each tumbler holds 15 ounces, striking a practical balance between refills and drink accessibility for growing kids. The fun Starpower-inspired design adds a playful touch to daily routines without compromising practical features like durability and ease of use.

These tumblers are built for real life: compact enough for small hands, yet sturdy enough to survive daily bumps and tumbles. The lightweight plastic shell is paired with a soft silicone straw, creating a comfortable sip experience for kids while the built-in valve helps the liquid flow when drinking and minimizes spills if the cup is jostled or overturned. The result is a cup that feels good to hold and easier to manage during busy days at home, in the car, or on a field trip.

In short, the Kelso 15 oz tumbler set combines dependable construction with a kid-pleasing design. Expect a comfortable sipping experience, straightforward cleaning, and the flexibility to use these cups at home, in the car, or on the go.
