One (1 pc) vacuum seal clamp that is tightened by the screw by hand. Can be used for nipples, genitals, etc. as long as a seal can be formed against the skin. This expands parts of the body one wants temporarily engorged. Increasing bloodflow may encourage growth in intimate areas as well as heighten sensitivity. Discreet option for temporary expansion of erectile tissues, rather than large penis pumps designed for cis men. Sizes 2-2.5 cm generally fit around AFAB erectile tissues while 3 cm will likely also pull the soft tissues around the phallus. For that purpose, we recommend sizes XS-M. A larger size can be used to pump the entire vulva, but we can not guarantee that those sizes will be able to seal. Any size can be used on the chest or nipples depending on how focused you want the suction to be! DISCLAIMER: Excessive hair can prevent a good seal against dry skin. Shaving or adding moisture/lube can help get much better suction.WARNING: When using against thin membranes, be careful the rubber base is not sticking out from the plastic cup to prevent pinching of sensitive tissues. Screwing this base all the way out however does help with cleaning the clamp after use. Show more
