At the OHTO Yuki factory, they designed and assembled this carefully crafted pen.

Easy to hold and the shaft is a beautifully shining shaft made of aluminum with alumite processing. It has an exquisite comfort that can be made into a unique shape that changes from a hexagonal shaft to a round shaft.

The core is an international standard G2 type. Oil-based replacement core PS-107NP black

It is a low-viscosity oil-based soft ink with smooth writing and can write with plenty of capacity for about 2,000 m., according to their written test. The pen tip is a Φ0.7 needle tip and the characters can be seen clearly.
