Zebra Clickart Water-Based Pen 36 Colors Set, Wyss22-36C

A click-type water-based color pen "clicker" That does not dry even without a cap has been released. Zebra has developed a new ink “moist keep ink” that absorbs moisture in the air and prevents it from drying without a cap, making it a water-based color pen that can be used just by knocking. This saves you the trouble of opening and closing the cap and allows you to easily use multiple colors. This product is easy to use for students who want to write class notes and illustrations using many colors.
