The just-as-good-but-not-as-pricey kroozie tumbler Raise your hand if you’re tired of overpaying for tumblers. Yea, us too. We got so tired of it that we decided to make our own. Turns out, it’s not rocket science. Our tumbler is just as insulating – if not more! – then all those other overpriced tumblers on the market. And we even added a powder coat for an extra layer of durability plus the option for some really cool colors. Keeps your drink cold for 24+ hours or hot for 8+ hours. Choose between 20 oz or 30 oz. Available in 11 fade-resistant colors. BPA-free, eco-friendly, non-toxic, food-grade stainless steel. Splash-proof lid with slider.
