These suckle just the nip nub (the center area about the size of a pencil eraser) and leave your areolaalone (the flatter area around your nip-nub).

These mini-suckers are made of Liquid Platinum Silicone, its the best rubber for suckers--they will not crack, crush or lose color firm enough for the right amount of pull but rubbery-soft enough to really seal to your nip with a wide flat flange around the base. They stay on and really feel like they are part of you. We include a carrycase to store NANO NIPS so they dont get lost in your piles of gear.
