Zebra Clickart Knock Sign Pen ST (Pack of 12)

Zebra Clickart Knock is an ingenious felt-tip pen with a retractable felt tip. The ink is specially formulated to resist drying for an entire year – as long as you keep it retracted when not in use. The ink remains moist by absorbing moisture from the air. Therefore, it is best if the pen is stored in a room that is not too dry.

This 12-pack contains the colors: black, blue, brown, gray, green, light blue, light green, orange, pink, purple, red, and yellow.

Can also be bought individually.

The pen won the Good Design Award 2019.
