The only 100 % pure grade US Silicon sex lubricant on the market. Do not be put off by the slightly higer price of Millennium as it lasts much longer than any water based sex lubes and you don't need as much of it to feel the benefit. It is a MUST for all lubricant users. Millennium really will last and last, even under water! Feels like silk, condom friendly however not suitable for use with silicon toys. The 2.5oz is the smallest Millennium bottle available and has a flip top lid. If you have never tried this product before this is the size to give it a go - it lasts so much longer than all waterbased sex lubricants. "It is one of the finest lubricants available" and has constantly been voted the number one sexual lubricants in the USA.
