Use the Stainless Steel Funnel to refill your 500mL Olive Castile Glass Bottle from the 2L refill whenever it runs low. Dispense the liquid wash onto damp hands or a washcloth for everyday hand and body cleansing. Use the Olive Castile Soap wherever a solid bar is more convenient, such as the shower, gym bag or while travelling. Store the 2L refill in a cool, dry place away from direct sunlight between refills.
