Opalite comes in such a stunning array of colors that you’d be surprised at the variety of jewelry pieces made from the precious stone. These single flare plugs are clear, but each plug will still be slightly different, though we’ll do our best to give you a matching set. They’re sold in pairs and come with “O” rings for holding them in place. Get yours in any of the following sizes: 8 gauge (3mm), 6 gauge (4mm), 4 gauge (5mm), 2 gauge (6mm), 0 gauge (8mm), 00 gauge (10mm), 7/16" inch (11mm), 1/2 inch (12mm), 9/16 inch (14mm), and 5/8 inch (16mm).
