Sheaffer Slim Cartridge for Fountain Pens (Set of 6)

SHEAFFER SLIM CARTRIDGE II FOR FOUNTAIN PENS.  These are empty, dried - out and not punctured. They will need to be cleaned out before use, but this slim profile isn't made anymore, so you can fill these with a syringe and use them in pens. Come 6 in a pack. Cleaning would typically be done by puncturing the front end with the puncture tube of a pen that it fits, flushing it out with a syringe and our Pen Flush or ultrasonic cleaning after filling with water and/or our Ultra Sonic Cleaning Solution. The pens that these fit also use a rare shaped/size converter, so these may rescue you if you have one of the pens that need them.
