Love these soaps
I'm in love with these soaps. I buy natural soaps all the time but these are my new favorite. Got it in my mouth on accident one time it was the oatmeal one, it was literally sweet no chemically taste.

Clean ingredients, nice soap overall but doesn’t have the best lather
4-stars because it doesn’t lather great, but all smell good and my skin is happy— good quality overall! Clean ingredients just as advertised. Just as a side note, the loofa bag it comes with is a bit too rough for my skin so I’ve been using a washcloth.
