Each marker features a 0.7mm bullet tip and measures 5-1/4" long, conveniently stored in a 6" square case. These markers use water-based ink and give the best results on light-colored backgrounds. To start the ink flow, gently shake the marker, then press the tip against a surface until the ink flows. Don't forget to recap the marker when you're done!
