Ole Acrylic Paint Markers - Set of 12 Medium Tips
If you have wanted to try paint markers but find the branded ones too expensive, give a non-branded marker a go, great for kids too
These paint markers have a priming tip (just like Posca and Flysea markers), so shake well before every use, prime tip to allow paint to flow, and remember make sure the lid is on tight when finished.
This packs has medium size tips, similar in size to Posca's PC-5M and Flysea Medium Tip (The pen barrel is identical to flysea medium pen)
Super bright opaque pigment ink, waterbased, waterproof (although on rocks still should have a clear top coat for damage protection)
