Cool Idea
I recently purchased this planning on using it for air brushed look backgrounds.
This is such a clever and unique idea for an art tool.
I tried it on several types of markers, hoping to use up several bunches of older less expensive markers, but they are not juicy enough to create the effect I was looking for. They mostly splatter.
The Marvey markers worked great. Not sure if it was because the nib is longer than some, or just juicier. The cheap brand markers would not work.
So, I will continue my search for the effect I want, purchasing more expensive and newer markers.
