PEBEOVitrea 160-Glass Paint Glossy Marker, Yellow Sun

Great pen

This pen has a nib where to you have to press the pen down repeatedly to get the paint to come out. I don't know if it's old or if it's been stored somewhere too hot but when I tried pumping the pen, the nib just smushed into a flat bristles clump and the paint never came through properly. I must have kept trying for 20 minutes and still no paint came through and the nib was completely wrecked.

Great for drawing on/ coloring plastics/ acrylics.

Works perfect on glass
