Providing ultra long-lasting, non-sticky lubrication, ID Millennium is super-concentrated to eliminate any chance of drying or dissolving, even under water!

Great for a sensuous, moisturizing body massage and for gentle skin conditioning, too! Made in the U.S.A.

As with any silicone lubricant, we do not recommend using it with any silicone adult toy because, due to a potential chemical reaction, the use of silicone lubricant on silicone adult toys may degrade the surface of the toy. Since silicone is extremely slippery, caution is recommended when using Millennium around surfaces like tile and hardwood floors which will remain slippery until washed with soap and water. To remove possible stains, use an extra strength detergent with a degreasing component.
