An empty Tribal marker for you to experiment and add any liquid you want to try.
From oils to paint to mud. The only thing to remember is there is a felt nib that the liquid mist pass through so nothing with particles or they won’t go through the tip.
So many other liquids or uses for skin therapies to art.
Your ideas are worth trying.
Will come with an extra nib as well
These markers will not have the tips cut and will be just rectangles.
