Why We Sell Thumler's Tumblers and Lot-o-Tumblers



We sell rock tumblers made by companies and people who we know and trust. Thumler's Tumblers (Tru-Square Metal Products) and Lot-o-Tumbler (BELT, Inc.) have each been manufacturing tumblers for about half a century. We personally own and use their products and have sold thousands of their tumblers to customers throughout the United States. We believe that they produce outstanding products, treat their vendors fairly, and take care of consumers who purchase their products.
