Sold as a pair, these 1 & 1/8" (28mm) are handcrafted from natural labradorite stone. Each plug has a stunning purple flash on one side and has double flares with a flare to flare measurement of 9mm. Move in the light to really see the flash at work! These plugs are a great option for your rare plug collection! Handle with care, as these are fragile and may break or chip if dropped.
