The Opus 88 Demonstrator is an eyedropper-filling fountain pen with a barrel made of alternating transparent and frosted resin. It is filled using the included glass dropper and holds 3.5 ml of ink. The rod running through the barrel regulates the ink flow, while the knob at the top unscrews to adjust the amount.
The cap screws onto the barrel, and the black clip is flexible. The pen has a broad nib.
