Diamine Fountain Pen Ink - Dark Forest, part of the 150th Anniversary Series, is a distinguished dark green ink in a 40ml triangular bottle. This special collection celebrates Diamine's 150 years of ink-making expertise, featuring 16 unique editions. The distinctive triangular shape of each bottle adds an artistic touch, forming a perfect circle when eight bottles are arranged side by side.

Diamine Espresso is one of the 8 New 150th Anniversary colours available in special 40ml bottles, it is a saturated dark colour like dark espresso coffee and it looks nicely sober without being dull. The flow is fabulous, so is the drying time, depending on the nib and paper in use.

Diamine, a reputable ink manufacturer from Liverpool, England, has been crafting quality inks since 1864.

These 40ml triangular bottles showcase Diamine's commitment to delivering solid inks at an affordable price, making them a staple brand in the world of inks.

In 2017, the 150th Anniversary Series was introduced as a second ink series, adding to Diamine's legacy. Espresso Bottled Ink is a non-toxic, water-based fountain pen ink compatible with any fountain pen, ensuring a smooth flow without causing clogs. Diamine's proprietary secret ingredient enhances the ink's vibrancy, allowing the colours to gracefully glide across the paper surface.
