Mix & Ready is an intelligent cartridge system which reduces packaging by 95% and shipping weight by 97%. The reusable spray bottles are supplied with two concentrate cartridges. Just fill the bottle with tap water up to the mark. Insert the cartridge into the neck of the bottle. Screw the collar back onto the container. The cartridge will automatically open. A quick shake of the bottle is enough and the cleansing agent is ready to use. By filling the bottle with water and inserting the cartridge with the spray head, one can get a cleansing agent in no time. The system prevents direct skin contact with the concentrate and significantly reduces the space required for storage.
