the Pilot Falcon, which has a semi-flexible gold nib. Some of Pilot’s higher-end pens bear the name of "Custom" or "Custom Heritage" and a two or three digit number. "Custom" models are cigar-shaped, while "Custom Heritage" models have flat tops and bottoms. The number is based on the year of introduction (from the foundation of the company—the Custom 74 was introduced in 1992) for models with two digits, while the third digit on models with three digits represents a list price when multiplied by ¥10,000 (the Custom 823 was introduced in 2000 and cost ¥30,000 at the time of introduction).
