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.

Great Value
I'm always looking for a deal on hand and body soap. For the price and what you get they're great. A couple of them aren't my favorite smells, but then again, that's the trade off I made.
