Swirl is a group of flavored water based lubricants, all glycerin and paraben free. Sliquid currently offers four flavors; Cherry Vanilla, Pina Colada, Green Apple Tart, and Blue Raspberry. New flavor formulations are always under way, including Strawberry Lime, due on shelves in late 2007. All Swirl formulations start with our Original 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, and will never cause yeast infections or UTI's.
