Proven Jelen core soap is ideal for hand washing and pre-treating stains. Our grandmothers swore by it, and its effectiveness is confirmed by modern independent tests. Thanks to the high share of uncolored soap, it is gentle on laundry while being highly effective.
Washing is easy: soak the laundry, rub with the soap, and gently knead. The soap is packed only in a paper box, which saves nature. Due to the absence of foil, water evaporation may occur and the weight may slightly decrease, which increases its effectiveness.
