Sailor introduced the first pocket pen in 1963 with the launch of the Sailor Mini. Platinum followed later the same year with its Poket PK-2000 (18k nib) and PK-1000 (14k nib). Pilot was the last of the big three to join the trend. Pilot introduced the Elite S in 1964. The "S" was meant to distinguished the new short pens from the full size Pilot Elite.

Pocket pens are designed with portability in mind. While capped, a pocket pen will measure less than 125mm from end-to-end. However, when posted, it becomes a full sized fountain pen. Pocket pens were popular in the 60's & 70's but recently have been making a comeback. Being easy to slip in a pocket or purse make pocket pens ideal for travel and those who are always on the go.

This Platinum Pocket Pen features an 18K gold soft-fine nib (the kanji characters in the nib denote soft fine). This also features the distinctive squared-off barrel end that was unique to Platinum. The pen is in (D) Fair condition. Platinum pocket pens will not accept modern converters.
