Measuring only 4 1/4" (10cm) long when closed, the X-750 has a chrome barrel and cap with a black rubber finger grip. The cap is removable and can be posted on the rear end of the pen to create a full sized, well weighted and balanced writing instrument. The rubber finger grip helps to prevent calluses while providing a very comfortable feel for extended use. This executive series of Fisher Space Pens is small, sleek and stylish. Utilizing the same dependable pressurized ink cartridges that allow our pens to write in all kinds of extreme conditions, they make a great gift for any special occasion!
