Using these Calexotics nipple clamps is a breeze. First, adjust the screws on the 4 - point press to set the pressure you like. You can use one or both clamps as you wish, whether you're playing alone or with a partner. The weights will add a great feeling as they move with your body. When you're done, make sure to clean them properly. Wash them with warm soapy water or use CalExotics toy cleaner. Let them dry completely before storing. Remember, these clamps are made of heavy - duty, non - tarnishing, nickel - free metal, but still handle them gently to keep them in good condition. And always ensure they're comfortable for you during use.
