Only yesterday, (At the time of writing this post), I uploaded my review of the new Arrtx Brush Markers or as they are officially called, the Arrtx Oros Sketch Marker. However, on that video I made a mistake and it is incredibly important that I highlight the mistake and rectify it. Another amazing YouTuber Lindsay The Frugal Crafter actually brought the mistake to my attention so I have Lindsay to thank for bringing this to my attention
