How to use

Load a 0.5 mm lead refill into the pencil according to the manufacturer's guidance, advance the lead by pressing the push button as needed, and adjust pressure to control line darkness. Replace the lead when it becomes too short or worn. Store the pencil capped or retracted when not in use to protect the tip and prevent accidental breakage.

Usage recommendations

Use standard 0.5 mm HB or B leads for general-purpose writing and drafting; choose harder leads (H) for finer, lighter technical lines and softer leads (2B, B) for darker, smoother strokes. Keep spare leads on hand for uninterrupted use and carry the pencil in a pocket or pencil case to protect it from damage.
