it all depends where you getting it from , which you did not state . but over the last several years (real) African Black Soap has been sold in quantities to be shaped and sold by the individual. it has the characteristics you stated , soft like play dough
and a brownish color. there may be slight variation in color depending on the region it comes from in Africa. there are different suppliers in the u.s and throughout u.k and Africa as well . i would recommend finding a sustainable collective out of africa or representative and buy direct from the source , if you are planning to carry it as a product , it will cut out the middle man and be a great help to the women that work making the product.
and yes the claims are true , i have family members that have used it for acne and skin problems which it help greatly .
p.s real black soap is hard to make outside of africa due to its technique and ingredients
