A range of two models that can be used according to the shape of the lead, the "standard style" that supports all weights with small through holes. ● Snake design that doesn't shift even with low weight. ● Snagless shape with less grass and dust. -A unique shape that increases the sense of unity with platinum. ● In consideration of the heavy line setting, the PE line is adopted for the drawing line.
