Looking for a brush that simulates the Zebra Super-Marble Gel Pen

Hi,

I’m not sure if this is what you’re looking for, but @mdfm28 made a brush preset very similar to what you described.

As a tip, you can set the layer blending mode to “Darken” or “Multiply” for the brush preset to create a similar effect to an actual pen drawing on paper.

I hope this helps!
