Using these nipple clamps is easy. First, adjust the clamps to a comfortable pressure level before attaching them to your nipples. Start with a lighter pressure if you're a beginner and gradually increase it as you get used to the sensation. The weights on the clamps will add extra pressure and create more intense feelings with your movements. You can enhance the experience by using a bullet vibrator on your erogenous areas while the clamps are on. When you're done, simply adjust the grip to release the clamps. As for maintenance, use a mild soap and warm water to clean the clamps after each use. Make sure to dry them thoroughly to prevent any damage. Keep them in a cool, dry place away from direct sunlight. Remember, always listen to your body and don't use the clamps if you feel any discomfort.
