This head has a very flashing effect, with a silver hologram and aurora processing. It shines so brightly, it's one of my favorites! I think it can be used for 3.5-4 inch octopus baits. Since it's handmade, please refrain from purchasing if you are looking for perfection. #OctopusBait #Kagura #LureHead #Bonito #Tuna #Trolling #Abalone
