The Theoni Kids Tumbler is a thoughtfully designed stainless steel drinkware option that brings together safety, style, and daily convenience. Built with double-wall vacuum insulation, it keeps drinks cold for hours—making it a perfect hydration companion for school, travel, playdates, or mealtime at home.

What makes it especially reliable is its uniquely crafted straw lid system. This design offers excellent spill resistance during everyday use, so even if the tumbler is dropped, tilted, or tossed into a backpack, parents can trust it to minimize mess. While a small amount of liquid may escape if turned completely upside down, in most real-world scenarios, it stays secure and leak-resistant.

Safe, Durable, and Parent-Approved

Crafted with premium food-grade stainless steel, the tumbler is entirely free from BPA, lead, and other harmful toxins—making it a worry-free choice for children. Its lightweight and compact build makes it easy for small hands to hold, encouraging independence from as early as six months.
