Ohto Graphic Liner Needle Point Drawing Pen - Pigment Ink - 0.05 mm. can't wait to get this in the mail! I am a loyal rapidograph user but i think the worst task ever is refilling/cleaning them or dealing with clogs and shit. i hate microns and other fibre tips for massively detailed illustration or lettering because i am so hard on the tips. maybe this will be my perfect pen!
