The available diameters are 6 mm up to 20 mm. A super breathtaking product at an unbeatable price, straight from your Factory. This stone plug is an all-natural product and is crafted from untreated raw materials. Therefore the product you receive may look somewhat different from the image. Please note: As many of our customers stretch their ears to different sizes, all our plugs, tunnels and stretching tools are sold as singles. If you'd like a pair, please add two of the same item to the cart.
