Love the smell of the soap and the net is very cool.
The soap smells great and the holder does a great job exfoliating my skin. It also helps to keep the soap from sitting in water and staying soft so the soap lasts longer.

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.

Not much lather
Hardly any lather but it doesn't make my sensitive skin itch.

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.
