Permanent Markers for Growth Chart / Height Chart - Black or Gold

We searched high and low for the BEST markers for our growth charts. The ink in regular Sharpie markers dries slowly, and the Ultra Fine Point Sharpie markers dries super fast but the line is VERY thin. We have tried them all and found the best of both worlds in our gold  and black markers.

✍ COLORS:
Gold metallic - medium fine point
Black - Twin Tipped - fine and ultra-fine ends
