Abstract
A fibre bundle is first formed from loosely entangled fibres. Then, the fibre bundle is encased in a plastic shell and dipped into a solution of a synthetic resin in a solvent to fill the spaces among fibers with the solution. After taken out of said solution it is left to stand for a period of time during which the volatilization of the solvent forms a great number of capillary passages for the transudation of ink. After grinding a marking pen is obtained having a nib and an ink reservoir integral therewith.
