Using these Calexotics nipple clamps is easy. First, adjust the sliding ring on the tweezer - style clamp to set the pressure according to your preference. You can use one or both clamps as you like, either by yourself or with a partner. During play, the weights will gently tug and move with your body, adding to the stimulation. When you're done, make sure to clean them. Wash them with warm soapy water or use CalExotics toy cleaner, then let them dry completely. Remember, these clamps are non - piercing and made of body - safe materials, but always use them with care to avoid any discomfort. Keep them in a clean and dry place when not in use.
