Zebra DelGuard Type-ER Mechanical Pencil

Zebra DelGuard Type-ER Mechanical Pencil 0.5mm

Eliminate writing interruptions with the Zebra DelGuard Type-ER Mechanical Pencil. Combining Zebra's iconic double-spring anti-break lead mechanism with a revolutionary capless inverted eraser, the Type-ER allows you to correct mistakes in less than a second. Simply flip the pencil upside down: the eraser automatically extends and locks firmly in place under gravity for wobble-free erasing. Flip it upright, and the eraser retracts effortlessly so you can immediately resume writing without ever fumbling with a protective cap.

Key Features

• Instant Inverted Gravity-Lock Eraser: Invert the pencil to automatically drop and lock the eraser in place for rapid, capless corrections; return to writing position for instant retraction.
• Patented DelGuard Double-Spring System: Dual internal springs cushion straight vertical force while deploying a protective metal shield against angled writing pressure to prevent lead snaps.
• Continuous Break-Free Writing: Allows confident, fast-paced note-taking and exam writing without fear of sudden lead breakage under heavy hand pressure.
• Ergonomic Textured Grip: Subtle matte elastomer grip section provides non-slip tactile control and cushioned comfort during long study sessions.
• Roll-Resistant Hexagonal Silhouette: Clean cylindrical barrel with a subtle anti-roll stopper prevents the pencil from rolling off inclined desks.

Frequently Asked Questions

• How does the Type-ER inverted eraser mechanism work?
  An internal gravity weight automatically deploys the eraser when the pencil is turned upside down and locks it securely against the barrel when pressure is applied. Once you turn the pencil upright, the eraser drops back inside.
• Does the eraser fall out or wobble while erasing?
  No, the internal mechanism firmly locks the eraser collar under pressure so it performs just as sturdily as a conventional fixed eraser.
• How does the DelGuard anti-break mechanism protect the lead?
  Vertical pressure causes the upper spring to cushion and retract the lead slightly, while diagonal or angled pressure causes the lower spring to push out a protective metal guide pipe around the lead core.
• How do I refill the lead into the Zebra DelGuard Type-ER?
  Pull off the eraser unit from the top of the barrel, remove the small stopper plug, and insert up to two 0.5mm lead sticks into the core reservoir tube.
• Are replacement erasers included or available separately?
  Yes, the pencil comes equipped with spare erasers and uses official Zebra Type Z eraser refills, which are easily replaced by pulling out the spent rubber stick.
