This unique pen by Pilot is a vacuum filler, with a deep transparent amber resin body, with a 14k nib and gold trim. The vacuum filling system allows it to hold 2.2 ml of ink, and has a shut-off mechanism that keeps the ink from coming out too fast. To write, simply turn the piston mechanism 2mm, and the locking mechanism will dis-engage. It is just under 6" long capped, and 5 1/8" uncapped, and the body is .5" wide. It comes with a bottle of blue Pilot ink.
