The Do Not Be Afraid Tumbler features a double-wall vacuum insulated stainless-steel design and a leak-proof plastic lid. The non-slip silicone pad on the base ensures a secure grip on surfaces, preventing spills and scratches. This tumbler can keep drinks cold for 12 hours or hot for 7 hours, making it the perfect companion for busy days. But that's not all - with each purchase, a portion of the proceeds goes towards providing healthy meals, clean water, safe housing, and education opportunities for children in Ghana, Africa through our partnership with the nonprofit A Better Life For Kids. Made with stainless steel, plastic, and silicone, this 20 oz tumbler is also top rack dishwasher safe for easy cleaning.
