Using these markers is a breeze. Just hold the marker like you would a pen and start creating. For thin lines, use the tip gently, and for wider strokes, press a bit harder. When you're done coloring, make sure to close the caps tightly to keep the markers from drying out. Keep them in the reusable case to protect them and make them easy to carry. If you accidentally get the marker on your clothes, wash it as soon as possible, and it should come out. Avoid leaving the markers uncapped for a long time, as this can cause the ink to dry up. Have fun creating beautiful art with these markers!
