Stack Soap is a personal care product developed to solve the issue of soap waste when an old bar of soap wears thin and would otherwise be discarded.[1] Stack Soap implements a grooved stack design such as that used with Pringles chips to merge an old, thin bar of soap with a new one.[2]

The concept was successfully pitched on Kickstarter in 2012,[3] and the product was featured in various media outlets including Wired Magazine, The Atlantic, Gizmodo, and market research firm Mintel.[4][5]
