• The Zebra Clickart Knock combines the fun expressiveness of a colorful felt pen with the convenience of a retractable ballpoint or gel pen.
• The ink is specially formulated to resist drying out for a full year as long as you keep it retracted when not in use.
• The ink stays wet by absorbing moisture from the air, so it works best if the pen is stored in rooms that aren't too dry.

Features:

• Convenient retractable design that won't roll away.
• Expressive felt tip.
• Winner of the 2019 Good Design Award.
• This set includes 12 colors: Blue Black, Blue Gray, Blue Green, Dark Brown, Green Black, Light Brown, Magenta, Red Black, Red Orange, Smoky Blue, Turquoise Blue, and Viridian.
