Frequently Asked Questions

• How does the "Frenock" shaker mechanism work? Simply shake the pencil vertically; an internal weight slides forward to advance the 0.5mm lead without shifting your hand away from your writing position.
• How do you lock the shaker mechanism to prevent lead breakage during travel? Push the pocket clip upward until it clicks into the "Lock" position. This deactivates the internal shaker weight so lead won't extend inside your bag or pouch.
• Can the built-in MONO eraser be replaced when depleted? Yes, the pencil uses standard Tombow ER-MG twist eraser refills. Twist the top mechanism to expose the spent core and snap in a new eraser unit.
• What lead refills are recommended for the 10th Anniversary MONO Graph? Any high-quality 0.5mm lead refill works smoothly, such as Tombow MONO-WX or Pentel Ain Stein leads in HB, B, or 2B.
• Does this limited edition come in special presentation packaging? Yes, the 10th Anniversary MONO Graph pencil is presented in an elegant commemorative Tombow presentation box, making it an ideal gift or collectible.
