OPUS 88 Koloro Fountain Pen - Orange
If you are a fan of eyedropper fountain pens, Opus 88 has a lot to offer!
The Koloro is a colourful series with a nice balance of ebonite and acrylic. The acrylic parts let us see the ink level and the fountain pen nib, which is both practical and nice to look at.
It utilizes a filling system that involves a shut-off valve. This design is commonly found in vintage Japanese eyedropper pens. This allows for a huge ink capacity and at the same time reduces the occurrence of ink burping commonly experienced in eyedropper pens.
The pen comes in a gift box with an eyedropper and user manual.
