Embrace the energy of the Manna™ Verve steel tumbler. This 3″ x 9.12″ x 3.5″ 18/8 stainless steel vessel has a thin and modern design with a twist-action sealing lid. Simply push the lid in either direction to take a sip, then push it again to create a leakproof locking seal. The double-wall insulation keeps drinks cold for 18 hours or hot for as many as 8. The BPA free construction is great for those that think green. Choose from two tones and add your organizational or company logo, emblem or message through our signature imprinting methods to customize.
