The massage head adds an adjustable massage feature to a bottle with shower gel. According to costumer needs the hardness or softness of the head can be adjusted by turning the ring. A silicone valve allows the perfect dosage of the product and also prevents water to move back into the bottle, hence the packaging can stay open upside down in the shower waiting for next usage.
