The 18 Series from KOKOS has finally arrived at ToyDemon. This is the Tattoo version. Called Tattoo because of the groove curve along the outside that looks like a tattoo pattern. These grooves improve the grip of the item during use. The design on the interior path is a slightly curve tunnel designed to give you a tighter fit. The textures of the wall are rounded ribbing to give a mellow sensation. The grooves between the ribs also help retain lotion during use. Around the middle of the tunnel, you will find a tiny nub lined structure for a great stimulation. Toward the end of the tunnel is a mini vacuum chamber and three nub stinger. The vacuum chamber helps to create a better suction feeling when you squeeze the air out as you insert. The stingers adds stimulation to this functional vacuum chamber. There are two version available, the lighter "Baby Skin" single layer 18 Tattoo and the darker colored "Real Skin" dual layer 18 Tattoo. The dual layer uses a harder material in the inside wall for even more stimulation. Please pick the version you want by the color picker above before adding to cart. *Please note that this product does not come with any lube or lotion.*Use only water-based lotion or lube with this product.
