Esterbrook Model FJ ballpoint pen ca. 1948 in Grey. Original refill has been modified to take a half mini refill. When the refill is used up, cut a mini refill to size of the existing unit and re-install. Screen imprinted for "Jobson Office Supply Plainfield N.J. PL 5 2938". Refill occasionally gets stuck in the outward position, simply press on a hard surface to retract if it does not do so automatically. Restored and in working order.
Be sure to check out our selection of Osmiroid nib units which thread right in to the esterbrook section for a unique writing experience!
**Vintage pens, or pens marked as Experienced will be considered for return only if they arrived to you as mechanically defective. Experienced pens may have small defects or scuffs, since they often have been pre-owned, and they have been priced accordingly. All Japanese Pen Nibs are graded as the manufacturer intended, that is, they will be finer than western counterparts (e.g. Japanese Medium is more like a Western Fine, Fine is more like an Extra Fine, etc.).
