If the lid is not covered for a long time, it will cause the pen tip to dry and hard, making it difficult to write ink.Due to the fact that the marker pen is a professional paintbrush, in order to achieve better color layering, it is necessary to use professional paper for painting. Ordinary paper may have ink penetrating through the paper.ABS
