The Rouge et Noir replica exists in two variants. The more expensive variant, limited to 100 pieces, takes over the historical safety filling system (slide pen) of the original, in which the nib is protected by sliding the mechanism in and out. The cheaper variant, produced in 15,000 pieces, is despite similar look a cartridge pen with a special slide mechanism: instead of unscrewing the nib as on the Bohème, the grip section together with part of the body is pushed backwards.
