What makes this water-based lubricant so great is that it contains hydrated silicone that delivers on its claim of being 3X longer lasting then any water based lubricant on the market. Plus it's hypo-allergenic and ph balanced which is very important for sensitive women. It's sugar free, odorless and non-staining and can be washed away with warm water. And it's still latex friendly. 1.9 oz. bottle!
