Our Borostone plugs are a mixture of two colors to create a swirl effect. Amber/Puple, Wavecrest, Purple Smoke, & Bloodymary are all mixed with a little clear to create a vortex on one side and vivid stripes on the other side. Black/White & Black/Gunmetal are both opaque colors mixed together & will produce zebra-like stripes on the outside. Each plug is a unique work of art, no two are alike. They are paired to complement each other. Must Purchase in Pairs. Double Flare only.
