Good product
Scent: Assorted
Good soap set I like the smell and the 4 pack last a good while. My only complaint about the soap is at the end it was soggy soap and hard to get it to dry. I will give the other bar a try if it does the same thing I might not be using this.

Scent: Assorted
I like this soap. It has great scent with adequate strength to support feeling fresh and clean. This soap easily cleaned my skin and removed body oils without making my skin dry or itchy or uncomfortable in any way. I also appreciate the cost is more friendly as compared to similar bar soaps with popular brand names.

If dye is an issue for your skin be cautious
Scent: Assorted
Crazy big bars of soap. Very fair price. Amazing smell. Lots of dye or something in the colored soap.
