Love these pasties!! They stick really well, and don’t seem to budge even when worn for an extended period. They also didn’t leave a residue. I liked that they have a ‘gap’ in the stickiness to avoid the nipple itself. You have to ‘charge’ these under a light source before they glow in the dark (I propped them up next to a table lamp for a few hours), and they lasted for about an hour before the glow started to fade. All in all, a fab novelty item to add to your collection!
