Swirl is a group of flavored water based lubricants, all glycerin and paraben free. Included in this 12pk: Cherry Vanilla, Blue Raspberry, Green Apple, and Strawberry Pomegranate. All Swirl formulations start with Sliquid's Original H2O water based lubricant, and add flavoring and a hint of Aspartame to sweeten. Flavors are subtle, and are intended to enhance, not disguise taste. All Sliquid products are formulated by sensitive women, for sensible women.
