Nipsuckers plump your nips making them more sensitive bigger and more “tingly.” Bigger nipsuckers (we make some seriously large and deep nipsuckers) might suck too much for smaller perky nips… NANO NIPS don’t.NANO NIPS are “just the tip” style nipsuckers. These suckle just the nip nub (the center area about the size of a pencil eraser) and leave your areola alone (the flatter area around your nip-nub).
