[[Geha]] entered the fountain pen market in [[1950]], with the production of economic pens made for the student market. The '50s pens were [[piston filler]] equipped with a special ink tank that allowed to maintain an emergency reserve. Later models passed to [[cartridge filler]], while maintaining the ink reservoir through the use of two separate cartridges, as for the [[Aurora]] [[Duocart]]. In the '60s were produced [[inlaid nib]] models similar to those of [[Sheaffer]].
