The Heritage collection pays tribute to the pioneering spirit of Roy Conklin and the golden age of fountain pens. All Heritage pens feature an inbuilt converter dispensing with the need for ink cartridges. The Heritage is available in 3 styles. The Word Gauge has a large view window with numbered gradations indicating how many words can be written with the remaining ink. The Sleeve Filler works like an integrated squeeze converter, and the Conklinetta Senior uses a simple push button mechanism with a lock to prevent leakage.
