These are accessories that can be attached to the nipples. They can be easily attached without piercing like earrings. I think they can enhance the body without causing any damage. Also, I think you can get a moderate feeling of tightness. Please note that depending on the shape of the nipples, such as inverted nipples, it may be difficult to attach them. Weight per piece: Approximately 4.7g The attachment part is made of silicone. Set of 2. Please refrain from purchasing if you are nervous or seeking a perfect product, as these are handmade items. Please refrain from purchasing if you have allergic symptoms, as they use non-metal allergy-compatible materials. Also, because handmade parts and imported parts are used, there may be air bubbles, dents, scratches, and size errors in the beads, etc. Regarding colors, there may be differences in the appearance between the actual product and the image due to the way the photos are taken. The items in the image are the products. Thank you. #Nipple #NippleRing #BodyPiercing #Nipple #AnonymousDelivery Color...Black系 (Black-based)
