Cross FP Cross Converter
CROSS fountain pens are not supplied with converters. Converters are used as a resuable cartridge and are filled using bottled ink. They are remebered for their squeezable sac but now use a more durable and reliable screw action to fill. The majority of CROSS pens fit converters with exception being the Classic Century and Spire models.
Their is two types of CROSS converters; a green push-in converter and a orange screw-in converter.
