P.W. Akkerman Fountain Pen Ink - 06 Binnenhof Blues

P.W. Akkerman Fountain Pen Ink in 06 Binnenhof Blues is a rich sapphire blue ink with a cool undertone that gives writing a clean and confident appearance on the page. The color feels deep without becoming too dark, and depending on the nib and paper, it can show subtle shading that adds a bit of character while still remaining highly readable. 

The ink has a balanced flow that works comfortably across a wide range of fountain pens, making it suitable for both everyday writing and longer sessions. It dries with a smooth, polished look and is often appreciated for feeling refined without being overly formal. Many fountain pen users also enjoy how the color develops as it dries, briefly showing a slightly purple tone before settling into its final blue shade.

Part of the appeal also comes from the iconic Akkerman bottle itself, which features the brand’s signature marble reservoir system that makes filling a fountain pen easier even when the bottle is running low. Named after the Binnenhof in The Hague, the ink carries a classic Dutch character that feels both traditional and distinctive among blue fountain pen inks.
