ECO PRODUCTS !!!! At the first stage the wool is washed in a stream with echo soap (no chemcals). Were guaranteeing, that the wool is in no way chemicaly processed - carbonized with strong chemicals, witch "eat" the dirt and plants from unwashed wool, witch are "stuck", in the sheep's wool while eating. The wool has saved as much natural substance as possible - lanoline (sheep sebaceous gland secretions), that promise that the wool heat's. The only chemical's used are the color - but even it is one of the best in Europe, made in Switzerland. And the chemicals in it are close to nothing. But without those unfortunatly there would'nt be any bright collors.This wool dyeing sectional.Price for 250g(8.81ounces).
