Opus 88 Flow

The Opus 88 Flow fountain pen is a large eyedropper-filled pen with a piston operated shut-off valve. The barrel is made of transparent acrylic with playful colored swirls and a solid colored resin cap. The cap and piston knob are octagonal shaped and features a silver stainless steel Bock nib. It also comes with a glass eyedropper to fill the pen with your favorite ink. An ebonite piston and rubber gasket seals the feed off from the barrel when fully depressed, reducing the risk of leakage and burping. By unscrewing the blind cap and loosening the rod at the rear of the barrel, you open up the ink flow to the feed. During long writing sessions, leave the shut-off valve open to take advantage of the impressive ink capacity.
