These nipple clamps are so easy to use - simply squeeze the clamps open and release onto your nipple. Because they are broad in shape, they're good clamps for beginners as they spread the sensation accross the nipple, rather than delivering a precise pinch. Remember don't leave nipple clamps on for too long to start off with - 5-10 minutes at a time is best for beginners. On release, blood rushing back into the nipple will make them incredibly sensitive and throb in a way many people find irresistable The chain between the clamps is good for gently tugging to increase sensation and the feeling of weightly chain swinging between breasts can deliver truly titillating sensations... Not just for nipples, clamps can be used on labia, clitoral hood and male equipment too - anywhere where a delicious pinch may feel pleasurable Care and Cleaning: Use Sh! Toy Cleaner, soap, 10% bleach solution or rubbing alcohol to clean; always rinse and dry thoroughly before storing.
