Trying out a new Acrylic Paint Markers set on glass - 30x40 cm
Besides the brush tip (which is a bit unpredictable), this set also have a bullet tip. When I need to go over the same lines more than once, it always behaves the same, which is super helpful.
The barrel is quite thick, so it doesn't flex, and there is a small ridge where the cap clicks that sits nicely in the pen holder. Sounds like a small detail, but when you're using almost all 24 colors like in this piece, it actually makes things easier.
In the end I didn't need any registration marks or alignment tricks! I even did the second pass after changing all 20 pens, just to be sure everything was fully dry before going over it again.
The paint is the usual fluid acrylic, just a shake, no pumping needed.

The glass is a 2mm floating glass from a clip frame, framed with a black backing
