Sell Zebra DelGuard Original Anti-break Core Mechanical Pencil Basic (0.5mm) best price

• Made in Japan • Unbreakable lead mechanism - protect your lead • Compatible with any brand of 0.5mm lead. • Never worry about lead breaking again! The DelGuard utilizes an ingenious two-part system that makes it virtually impossible to break the lead. • First, a spring in the barrel of the pencil lets the lead slide back into the pencil instead of breaking if too much vertical pressure is applied. • Second, another spring in the tip dynamically extends the lead guard to protect the lead when too much sideways pressure is applied. It may sound complicated, but it really works! • And without the annoyance and interruption of breaking leads, you'll find your concentration greatly improving. • Delguard system installed - Protect the core from all directions • Vertical Force : 1. Upper spring absorbs writing pressure / 2. Prevents breaking by escaping the core upward • Diagonal Force: 1. Lower spring absorbs writing pressure / 2. Tip jumps out and guards core • Delguard protects up to the lead protruded by 4 times of press. If more than 4 times of press, the lead might subject to breakage. #Zebra #DelGuard #Anti-break #MechanicalPencil #JapanStationery
