Frequently Asked Questions

• How durable is the 0.5mm ultra-fine tip under writing pressure?
  The 0.5mm nib is reinforced with a durable collar to prevent tip splay and bending, ensuring a consistent hairline width even during prolonged fine-detail sketching and labeling.
• Will the ink smudge if touched immediately after writing on plastic or metal?
  No. The quick-evaporating solvent vehicle allows the oil-based resin to set within 2 to 3 seconds on smooth surfaces, effectively preventing finger smudges.
• What colors are included in the Mixed Pack?
  The Mixed 12-pack contains 6 Black markers, 3 Blue markers, and 3 Red markers, offering an ideal ratio for daily office filing and editing workflows.
