J-Lube is a concentrated powder that dissolves easily in water and is a very effective obstetrical lubricant. J-Lube is completely inert and non-irritating.
One 284 gm (11.2 oz) plastic bottle makes approximately 22-30 litres (6-8 gallons) of extremely slick, water-soluble lube. You can mix to the consistency you desire...even pre-mix it and store it for later. Safe to use with latex, silicone, and all your toys. The preferred lube for fisting because of it's consistency, slipperiness, and easy clean up.
J-Lube breaks-down naturally in the body, and a few grains of table salt breaks down J-Lube on surfaces.
