Sliquid Naturals Swirl are our flavored water based lubricants, all glycerin and paraben free. All Swirl formulations start with our original Naturals H2O water based lubricant, and add flavoring with a hint of aspartame to sweeten. Our subtle flavors are intended to enhance taste, not disguise it, helping to take your intimate experience to the next level. New formulations are always under way, and we encourage our customers to send us ideas that they would like to see!
