Pilot Petit 1 fun, pocket mini size fountain pen comes with transparent pen barrel and cap. The color clip on the cap indicated the matching ink color for the fountain pen. The fountain pen fitted with the clear transparent ink feeder, which allow you to see the fast ink flow to nib. Superb smooth nib for both writing and doodling.
