Every buy ink just for the bottle? I can now say that I have. P.W. Akkerman’s bottle is both beautiful and highly functional. The small reservoir at the top of the bottle is narrow and deep allowing even large nibs to utilize a near empty bottle. There is a glass marble inside the reservoir that when turned on its side allows ink to flow into the neck of the bottle. This is without a doubt the best ink bottle design I have seen. The Montblanc shoe and the old American-made Sheaffer Skrip bottles are good but the Akkerman bottle is great.
The most interesting color out of the 30 different Akkerman inks is #24 Zuiderpark Blauw-Groen which is a nice dark blue green ink with good shading and flow. My first thought was that it looks a lot like Private Reserve Ebony Blue, which in my opinion is one of the best looking inks around.
The ink isn’t waterproof but it did resist the water better than many other non-waterproof inks and that makes me a little bit concerned about leaving this ink in a pen beyond a couple of weeks; that said, I was able to clean this ink out of my Aurora Optima without problem.
#24 Zuiderpark Blauw-Groen (excluding VAT) costs 12.4 EURO or about $16.35 USD which is a reasonable price for this great 60ml bottle of ink BUT the shipping is quiet expensive. 20 EURO or about $26 USD shipped to the United States. Because of the high shipping cost I ended up buying three bottles. Is it worth the price? I think that depends on how much trouble you have filling your pens with large nibs. For me not having to buy two bottles of the same sink so that I can top off one with the other is valuable.
