Thank you for viewing. These are homemade foam sinkers. They are painted orange. The coating is UV resin. The weight and shaft are soldered together inside. The shaft is reinforced with plastic around it for added strength. 20g x 3 pieces How about using them for pulling for Japanese whiting? I use them, and they don't tangle as much as longer types, and they fly well. I've had good fishing results with them. Since they are handmade, there may be small scratches. Please refrain from bidding if you are sensitive to imperfections or seek perfection. Please bid only if you understand.
