The plastic of the Soapis is recycled from approx. 90% disused fishing nets. So this plastic no longer ends up in the seas, but in a new form in your bathroom in the long term. Instructions: Stick your Soapi to a flat and clean place. Now press a bottle cap half into your soap and hold both briefly under water so that the bottle cap connects more firmly to the soap. Allow to dry, done! Thank you for not buying shampoo in plastic bottles anymore!
