My newest addition to the wacky line of products: Stainless Steel Tumblers! These double wall insulated tumblers are sure to keep your favorite beverage at the right temperature. Each tumbler features a slide-lock lid to prevent spills. But the best part is the wacky art available for the first time on a tumbler. My words of widsom for mothers, sisters, friends and sons and daughters make the perfect gift for wacky friends and family. 16oz capacity stainless steel mug.
