The 88 model was equipped with a very advanced piston filler, with differential threads. The pen was made with a metal cap in both gold-plated metal or using an alloy of nickel and silver called Nikargenta. The body was in celluloid with a transparent section, while the handle of the piston was in hard rubber. The 88 was qualitatively and technologically far more advanced than a 51, the only plastic part was the sheath of the nib, and the feeder had a sophisticated supply system which allowed a regular ink flux.
