Mess-free and easy-to-use concentrated foaming hand soap refill. Made with essential oils, aloe vera, olive oil and other thoroughly chosen ingredients. You can use this concentrated refill in either the brand's 10 oz reusable bottle or a standard plastic bottle. One tiny 2 oz concentrated refill, diluted with water is equal to one 10 oz of soap. Fill a 10 oz bottle with water to the fill line, add one 2 oz bottle of the concentrated refill and attach foam pump. Gently shake a few times until dissolved then pump away. When the bottle is empty, rinse well with water and repeat.
