Looking for the perfect pocket pen? Might we suggest the Pilot M90 fountain pen. This steel wonder fits in any breast pocket, but it can extend to full length when writing! Its long cap and short barrel make it the perfect go-anywhere pen. Another unique feature is is steel barrel that forms into its nib! It is a very clever design. Plus, this pen comes with its original Pilot converter. You also can use Pilot proprietary cartridges. You will write a firm-but-smooth extra-fine line. We also like the blue-jewel accent in the top of the cap. Click the headline for close-ups. 11.8cm capped.
