Finally, choosing brand X is a good thing! Astroglide X is a new "premium personal lubricant," which really is just a fancy way of saying it's silicone lube in its purest form. The only ingredients are cyclomethicone and cyclopentasiloxane, two types of high-quality silicone, making Astroglide X an extremely long-lasting, condom-safe lubricant. The mainstream-friendly label and packaging doesn't actually use the word "silicone," so be sure to let customers know, particularly if they are purchasing a silicone toy. $
