The Sign Pen is Pentel's cult classic, known since the 1960s. It features a sturdy design, a durable nib, and is filled with water-based ink.

The Sign Pen became world famous in the 1960s when President Lyndon B. Johnson used it. It was later named the official pen of NASA and went into space in 1966, hidden in the shoulder pockets of astronauts Richard Gordon and Charles Conrad during the Gemini 11 mission.

Famous or not, the Sign Pen is perfect for:

• Writing
• Sketching
• Drawing

Perhaps the Sign Pen has maintained its star status all these years because of its:

• Extra-durable tip that never gives way
• Water-based and colour-intensive ink
• Smart snap-fit cap that prevents the pen from drying out
