A pretty good substitute for Buttered Popcorn, but. . .

I would LOVE to say I really dig these yellow inks, but they are SO LIGHT! Unless you are writing with a stub or a REALLY juicy broad or maybe a medium nib, they just come out too light.

Pleasantly surprised.

I never had much interest in yellow inks before but I wanted to experiment for a project and among the samples I tried, this one was surprisingly legible. Fun for art projects as well.

Delicate yellow.

I inked up with the Rohrer and Klingner Helianthus yellow with much anticipation. I found it to be a pleasing delicate shade, which would have been terrific for colouring or drawing. However when it came to writing with it, the colour was too light to really be easily seen on the page. It was paler than I anticipated, so alas it was thumbs down, as I prefer a darker colour for any handwriting I may be doing.

Exactly as advertised

I bought this when I really wanted a sample of Rohrer & Klingner Alt Goldgrun and thought why not try 2 samples of their ink while I'm at it, these samples aren't expensive. Its bright yellow just like it says, but its still more visible on the page than other yellow inks I've tried.

Nice color, a nice yellow that shows up well on most paper

FAQ about Ink Samples

How do I fill my fountain pen from an ink sample vial? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It depends on the fountain pen's filling mechanism.

Check out our blog post on How to Fill a Fountain Pen from an Ink Sample Vial.

How much writing can I do with 2ml of ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It really depends on how big or small you write, and the nib size you’re using. We find that usually you can get 2 good fills for a typical converter with our Ink samples, or one good fill with a piston-filling pen. How much writing depends on you more than anything else, so we recommend experimenting with different nib sizes to find what works best for you. 

What is shading, sheening, or shimmering ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Shading - A common (and often desired) result of a fountain pen ink pooling in certain parts of a letter when writing, so that the color and saturation of the ink appears different within a single letter or word. This characteristic cannot be achieved with ballpoint or rollerball pens and is a very appealing aspect of fountain pen use for those particularly drawn to all the pretty ink colors.

Sheen - Characteristic of a fountain pen ink where when ink pools another color can be seen on top of the ink, especially when looked at in different light angles using certain paper types. There is no way to guarantee an ink will sheen, but using a larger nib on a pen will help obtain sheening results in your writing.

Shimmering - Fountain pen ink that has small particles of glitter mixed in.

Is shimmering ink safe to use in fountain pens? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Yes! Shimmering ink is a great way to add some flare to your writing. We have found that a larger nib will showcase more shimmering particles while writing, but you can use any nib size and shimmering ink. All the ink we sell is safe for use in fountain pens.

You can learn more in our blog: How to Write with Shimmering Ink.
