Cosmo is a visual and textural dream. The shaft curves up a wonderful arch and the horizontal ridges play on the mons with or without the vibrator being turned on. This 100% silicone vibrator is completely harness compatible with a removable Variable Speed Micro-Mini Vibe, which fits perfectly in the base. Silicone is a very dense material and carries vibrations very strongly all the way up the shaft to the tip of the top head. It is safe for anal or vaginal play. Because it`s silicone it`s flexible, warms to body heat, hypoallergenic and hygienic (boilable and bleachable in a 10% solution). The silicone dildo should be separated from the battery vibrator before cleaning. You`ll find it easier to remove the bullet if you put a small drop of lube on the tip before inserting it. Dimensions: 1.5" x 6.5" Requires: 3 x watch batteries (supplied)
