Sizing up in metric units makes sense for the transition between 5/8" inch and 3/4" inch. Since this gap is quite large, an in-between size like 17mm reduces unnecessary damage to your piercing by providing a stopping point. Thankfully, UBJ’s got you covered with 17mm plugs to simplify this jump. Both plugs and tunnels are available in single flare variations to fit any need or requirement. Materials like stone, glass and stainless steel ensure more than just the basics for your collection of stretching jewelry. Find a 17mm style that suits you and give your piercings the rest they deserve!
