Elong Nipples suckers work…and look so cool. They will suck any size nip and are deep enough and big enough to fit small to medium piercings. These stay on- the base flares out for more contact with skin. What gives them powerful suction are the four springy rings that make the nipple-tube pull open without collapsing like other suckers.
