DelGuard 0.5mm Light Green

This amazingly designed mechanical pencil features a two-part system to prevent the lead from breaking while you're writing! A spring in the barrel of the pencil allows the lead to move back into the pencil with too much vertical pressure; too much sideways pressure will trigger another spring to automatically extend the lead guard.  Features a smooth light-green plastic barrel, and comes with an 0.5mm lead.
