SB6E-XF\u00a0Two-tone extra-fine stainless steel flexible nib in a Bock 250 housing and feed manufactured from black ebonite. Fits all pens that use a Bock 250 cartridge converter nib assembly.<\/p>\n

This stainless steel flexible nib is manufactured in India. The nib has been combined with an ebonite feed and housing to provide optimal ink flow for the flexibility that this nib provides for calligraphy or art. See writing sample below for this nib’s capabilities.<\/p>\n

The nib’s tines have been adjusted for best writing experience. The nib assembly is tested with Pelikan 4001 Royal Blue on Clairefontaine French Ruled paper. There may be some ink residue present from testing, so be sure to flush with water after installing the nib assembly into your pen.<\/p>\n

Installation Instructions<\/strong><\/p>\n

To use the SB6E-XF nib assembly in your Bock 250 compatible pen, you will need to remove your Bock 250 nib assembly.\u00a0For most pens that use cartridges or a cartridge converter, unscrew the pen body to reveal the cartridge or converter. Remove the cartridge or converter (if your pen has ink in it, follow your usual routine to remove the ink from the pen first), then unscrew the section from the pen body. Remove the cartridge converter, if present. Next, unscrew the nib assembly from the pen. To do this, using two fingers on only the body of the nib (do not touch the tip of the nib, or the tines), gently unscrew the nib in a counterclockwise direction. If you have allowed ink to dry in your pen, you may need to soak the nib and section in water or soapy water for a few hours to dissolve the ink residue.<\/p>\n

Take the SB6E-XF nib assembly, screw it into the section of the pen, re-insert the cartridge converter, and fill the pen with ink. \u00a0If you are using a cartridge instead of a converter, then you will need to puncture the cartridge with the Bock 250 housing, our housing\u2019s converter nipple doesn\u2019t have a sharp tip. Screw the body of the pen back on, and you are now ready to write.<\/p>\n","protected":false},"excerpt":{"rendered":"
