Durability of liquid ink
The durability of the liquid ink has so far been tested for about 6 months, and during that time there has been no mold or other deterioration of the ink. Therefore, the durability of the ink for a period longer than six months cannot be guaranteed. We recommend that you always pour a smaller amount that you will use, and keep the rest refrigerated. For this, we can recommend our mini ink bottle.
Ink colorDo you need to lighten or darken the walnut ink? If you want to achieve a lighter shade of ink, simply add a little water. If, on the other hand, you need the color to be more intense, leave the ink bottle open during the day/night to allow some of the water to evaporate.
