Sliquid Naturals Swirl is a group of flavored water based lubricants, all glycerin and paraben free. Blue Raspberry is part of the new flavor formulations that start with our original Naturals H2O water based lubricant, and add flavoring and a hint of aspartame to sweeten. Our flavors are subtle, and are intended to enhance your taste, not disguise. All Sliquid products are formulated by sensitive women, for sensible women.
