Akkerman Inks
The faceted ink bottle is characterized by the long-neck, in which there is a glass marble. By tilting the closed ink bottle, the neck of the bottle fills itself with ink. When the bottle is put on a flat surface again, the marble will fall back and prevent the ink from flowing back into the bottle. In the neck of the bottle there is now a small reservoir and you can easily fill your fountain pen, even when the pot is almost empty!
Backpack Ink
Formulated for fountain pens, crafted for every day carry
The Ink
Conventional fountain pen ink can consist of up to six types of ingredients:
- solvent (water)
- colorant (dyes)
- humectant (wetting)
- surfactant (flow)
- preservative (biocide)
- buffer (pH)
Our fountain pen ink has only three total components because our binding agent acts as humectant, surfactant, and preservative all in one. Our well-behaved ink flows medium-wet yet dries fairly quickly.
The Bottle
Our fountain pen ink is dispensed in a small 20 milliliter transport vial. We chose plastic vials over traditional glass bottles for several reasons:
- appropriate for storing chemical solutions
- leak proof
- shatter resistant
- easy to carry
- no bottleneck
- recyclable
- inexpensive
