The Opus 88 Halo fountain pen is part of a co-branded collection featuring the genius of Opus 88 and Lennon Tool Bar. The collaboration features the same dimensions as the Opus 88 Koloro fountain pens, but the Halo pen collection is transparent! Each pen's featured "color" is shown on the pen's section. Each Opus 88 Halo fountain pen comes with a LTB threadbound pocket sized notebook (soft cover is sage colored and pages are white with a lt. gray dot grid pattern).
The transparent barrel allows you to view the ink level at all times. The Opus 88 Halo fountain pen is designed specifically as an eye dropper fountain pen with a control knob and center bar inside the barrel to help control ink flow. This type of eye dropper system is typically only found among high-end fountain pens.
The Opus 88 Halo fountain pen is fitted with a stainless steel #5 nib, and comes with a small bulb eye dropper to fill the pen with 2ml of ink.
