NATURAL AND BPA FREE - We made this set of 3 soap dispensers from PET plastic. We chose PET plastic because it is strong, thermally safe and does not contain any hazardous chemicals or compounds. Each donor is free of BPA - a harmful toxin that can enter the human body and cause cognitive and developmental issues. Our soap dispensers are safe - and we'll give you full instructions on how to use them. EASY TO APPLY - Used primarily with Castilian soap, just add water for a nice lather effect and extend hand washing time. LESS WASTE - Instead of throwing away your empty soap containers, simply fill them with liquid soap and water to reduce plastic waste IT'S FRIENDLY (FOR YOU AND THE ENVIRONMENT) - We made this set of foam soap dispensers for use with Castilian soap for two reasons. One less thing is that the soap is used every time you wash your hands. Commercial soaps use mixtures of harsh synthetic detergents. Castile soap uses natural oils to clean your hands without over-drying or damaging your skin. It's biodegradable and won't clog drains - clogs that typically require costly visits to a plumber or harsh, harmful solvents to clear the clog. Our reusable foaming soap dispenser is made of PET plastic and is BPA free. It is user friendly, all natural and reduces plastic waste.
