I decided to give these paint pens a try when I was looking for paint markers with vibrant, saturated colors that would cover almost any surface, but without having to use oil-based toxic paint. The MingNor variety set came with all the colors I needed, plus more, and the acrylic paint completely covered everything I needed them to. I highly recommend these paint pens to anyone looking for bright, full coverage pens that are water based instead of oil-based.
