Selling a rare & discontinued Conklin Mark Twain Crescent Filler in the Limited Edition Rainbow PVD finish, engraved with the highly coveted serial number #0000.

While the standard production run was limited to 1,898 pieces, a #0000 designation indicates a manufacturer’s prototype, artist proof, or retail master display sample.

The pen features a solid brass construction coated in a brilliant, multi-tone rainbow PVD finish. It utilizes the vintage-style push-actuated crescent filling mechanism with a smooth, black-plated steel Medium nib featuring the signature crescent breather hole.

This is a pristine "catch and release" that came directly out of an official retailer mystery box. It is completely uninked, dipped, or used. The black-plated nib, feed, lock-ring, and internal ink sac are in flawless, factory-fresh condition.
