VMC Octopus hook serves as the frame of VMC Resin Octps color hooks. The hook is made of forged "Hi-Carbon-Steel" steel, so it can withstand even rough going without bending. Ultra Glow color mixed with epoxy glows for 15 minutes after charging. Charging can be done e.g. with a flashlight or in sunlight, or more efficiently with a Rapala UV charger. There are two color hooks in the package.
