New Ontherun OTR.988 Ball Pen Ink Gel Fluid 100ml Refills

Those in the trade know that to create their own marker inks, the gel from classic BIC ballpoint pens is often used to thicken the ink. An operation that requires many pens and generates a lot of plastic to throw away. Now it is available directly in bottles and in 3 different colors!

With this large format you save a lot and you can use the fluid gel for:

Modify your inks and paints

Make colors deeper, darker and denser

Refill all your metal tip markers

Capacity: 100ml

Use no more than 10-15% concentrated ink for any mixing with other paints and inks.
