No, these plugs aren’t oily, but they do look like drops of shimmering oil.
The double flare plugs have a round shape and simple grey color, but reflect a rainbow of tones in the light. Due to the nature of the material, each and every plug is unique, but we’ll do our best to provide you with a matching set since they’re sold in pairs. Keep in mind also that sizes 12G – 00G have an 8mm wearable area, sizes 1/2″ – 24mm have a 10mm wearable area, and sizes 26mm – 30mm have a 12mm wearable area.
