High quality piston converter for pens that accept International size cartridges, enabling use of bottled ink. If your pen takes cartridges that are 38mm long and tapered towards the nib end then this converter will probably fit. This model fits fits the Pelikan Celebry, Pelikan Epoch and other Pelikan cartridge/converter pens that take International standard (short) and long International size cartridges. Maximum diameter 7.7mm, length 75.5mm. It will also fit Conway Stewart, Yard-O-Led, Edison, Bexley, Rotring and other models listed on this page
Please also note that these converters will not fit the Conway Stewart Dinkie or Yard-O-Led pocket fountain pens as these models have a short barrel and hence are cartridge only. For other pen models, if you are in doubt, check that the barrel has enough space for the converter before fitting into the nib unit.
