Here are the Amazon (affiliate) links for the markers I use in the video: Posca Extra Fine Tip: These have excellent coverage and last a lot longer than most acrylic paint markers. They do cost a bit more than other markers.  Recheel Dual Tip 72 count: I especially love these markers because they have a fine tip on one side and a brush tip on the other. I like to use the brush tip for larger spaces. These paint pens are much more affordable, but do not last as long as the Posca. Also comes in a 30 count and 48 Count
