Cross Century II 10K Gold Filled/Rolled Gold Rollerball Pen The Century II Rollerball Pen is the modern version of the original Cross profile with a popular medium-diameter barrel, conical top and single cap ring. The 10K gold-filled/rolled gold finish is greater in gold content than gold plate and is a fine example of Cross' unsurpassed craftsmanship. The gold-filled finish can be beautifully engraved and makes an outstanding gift choice. The Selectip rolling ball pen can write four ways with the change of a refill.
