Inkebara
Inkebara inks are handmade in Czechia.
Inkebara inks are water-based and due to their non toxic, water based properties (no solvents, oils or alcohol) they are applicable to use in both vintage and modern pens. In fact if you find the ink has dried up in your pen, it can simply be re-diluted with a drop of water. They are arguably one of the safest and reliable inks to write with today.
