Bar Soap



Lather up and indulge with these cold-process soaps. Handmade in small batches by Mater in New York City, each soap is made from sustainably-sourced plant materials – so you can clean up the way nature intended. 

Mugwort: Made of ground mugwort and olive leaf to invigorate circulation and warm the body. Coriander and sage essential oils linger on the skin with a bright and clean aroma.

Geranium: Our most gentle and nourishing soap, this bar is similar to a traditional castile soap. The high content of olive oil makes for a soap perfect for delicate skin.

Sea: Made with avocado oil and mango seed butter, this bar softens the skin with sea minerals and carries a hint of rosemary essential oil.
