Using these vibrating nipple lassos is a breeze. First, place your nipple inside the lasso. Then, slide the clear bead down to get the right tension that suits you. Once you're comfortable, just flick the switch, and the powerful vibrations will start. It's important to clean the lassos after each use. You can use mild soap and warm water. Make sure to dry them thoroughly before storing. Also, keep them away from sharp objects to avoid damaging the silicone. Don't use them with any oil - based lubricants as it can harm the material. If you have any skin sensitivities, it's a good idea to test a small area first.
