Stack soap avoids the awkward “sliver stage” by combining your small bar with the next fresh one. Designed with a special groove, each new bar is ready to receive the previous little sliver. They’ll join together and meld into a single bar. You’ve now begun the Infinite Cycle of Soap.

Stack is an all-vegetable soap infused with jojoba oil to moisturize and protect sensitive skin. Oh, and there’s no sodium laureth sulfate (SLS) to mess up the oceans.
