The Coggin Lures Copalure Invert has 12" skirt saddles with a zero-angled inverted/cupped nose with 4-hole jets. Double tapered with the "hump" pretty much in the middle of the head with a deep cup. Head is very similar to the Medium Copalure Invert except that it is about twice as long - same skirt saddle size. Awesome head for Ono/Wahoo, Ahi/Tuna, and Marlin.
This particular head has iridescent purple/blue dichro glass inserts with a purple sparkly back. The amount of color projecting off this head is truly amazing - Pictures do not do it justice. Skirted in black/purple glitter over white/blue/black rainbow.
