Reliable even under pressure! The STABILO SENSOR has a unique spring-loaded tip to optimally adapt to any writing pressure. In this way, the hand always remains relaxed, even after prolonged use. The micro-springing prevents the tip from bending or, in the worst case, even breaking, making the pen a long-lasting companion. The metal-encased tip ensures high quality and allows excellent writing comfort. Because of the smudge-proof ink (blue and black), it is also popular with left-handers and ideal for hand lettering and color tangles.
