Herbin 11553T - 10ml bottle of ink for fountain pens and rollerball pens (product without packaging - zero waste objective), Jaune bouton d'or/Buttercup yellow

This is one of my all time favourite shades of grey ink. It's dark enough to see but also light enough to be pale grey. I use it in colouring books and it's great for clouds.I'd definitely buy it again.

Lots of subtle greys when you use this. Not suitable for anything that needs to stand out though.Gave it one star for flavour because I don't know what else to put. I'm assuming it wouldn't taste very nice because it's ink.

A little light in color at times, so it takes a bit of trial and error before getting the hang of how to work with it, but I like it as it makes for a change from black and blue ink.

This is the most magnificent ink. I've been using it for drawing and I absolutely adore it. Will be using this colour again and again AND definitely recommend J Herbin inks.

Wonderful pink ink. These small bottles are very useful to take out and about. So easy to refill my pen in the upright shape.

The Quality of the ink was very bad, extreamly runny and water like. the color is much lighter than what is looks like hard to read on paper. do not recommend!

Dark charcoal grey in the bottle but much paler than expected when written on paper.

A neutral grey ink and a hard-to-find shade probably best used on a bright white paper. As a lighter tone, it is ideal for the broader nib, possibly with Medium being the minimum you would want to use.The brand of inks tends to need a long-ish drying time, at least 30-45 seconds as it it will otherwise easily smudge, although that may depend upon weather or room temperature. The ink can shade within a stroke and become darker towards the bottom although quite transparent within some areas. With different papers, it can feather fairly extensively on some but not at all on others. However the ink is quite expensive for the quantity provided especially in comparison to other brands. It needs be noted that the ink uses natural dyes rather than synthetics and have been considered by several specialist reviewers as 'too thin' or transparent although easy flowing.From a practical viewpoint, the bottles are small and with a narrow neck that is not amenable to certain styles of fountain pen, one example filling to a wholly unacceptable 25% of capacity. Also the bottles appear to be designed with dip or artists' pens in mind as a pen rest best suited to their size is moulded into the top of each bottle, too small for other than a few fountain pens. Even if a fountain pen is narrow enough to be dipped into the bottle, it will probably fail to fill after a small number of uses as the bottle is ill-designed for the purpose (too squat). The ink is easily washable which may be a bonus should you get some on fingers or clothing but it is equally transient on paper and susceptible to moisture or steam. It has also been noted on several specialist fountain pen sites that Herbin inks have a tendency to clog many brands of pen from the minimally expensive upwards and including several Mont Blanc models (a brand not normally known to clog, ever), in which event the pen will need to be re-filled several times in lukewarm water to dissolve its residues.In view of the practical limitations in its use, this ink cannot be recommended and those purchased are to be returned..
