The double-can insulated holder, designed to fit standard vehicle cup holders, keeps a backup drink chilled and accessible within a single sleeve. Beier conceived the product while struggling to keep refreshments cold while floating with friends, eventually refining the design into a commercial offering that earned a finalist spot for the 2026 International Housewares Association Global Innovation Award.

Stack 'Em has grown beyond its initial prototype phase to include a 16 oz model for slim cans and a variety of color options. Before this latest retail deal, the product established a presence through online channels and major retailers like Scheels and Amazon. While the company highlights this placement as a success, InventHelp notes that such commercial outcomes are not guaranteed for every inventor utilizing their development and submission services.
