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!
