Every bar of soap spends its final days as a tiny, impossible to grip sliver, inevitably ending up in the trash – or worse, clogging up holes in your shower drain. Stack Infinite Soap puts this issue to rest with a particularly grippy (and clever) groove, fusing with your older, worn down bar of soap; when it ends up a sliver itself, fuse it with the next Stack bar, and so on. Infused with Shea butter, the lightly-scented soap won’t strip your skin of natural hydrating oils and has thus far received highly favourable reviews.
