The spring retainers provide spring support, reduce stress concentrations, and increase strength and reliability.

Great lather
I bought this for my husband and he loves it so much, I will have to try it myself! He says there is no scent at all and it lathers very well.

Will order again!
This soap worked wonders for my psoriasis. It was very gentle on my skin. The bars lasted a long time which I feel like made it worth the money. The ingredients being all natural is also a plus for this product. While it didn't make my psoriasis flaw-up go away it did help with the itchiness of the areas. And it just soothe my skin.
