DelGuard Sharp Mechanical Pencil 0.7mm / Zebra

The DelGuard Sharp Mechanical Pencil's protective design prevents lead breakage no matter how strong your writing pressure is. As you apply strong pressure that is perpendicular to the surface of your page, the spring within the pencil will release the lead upwards to prevent the lead from snapping. If the pressure is applied at a diagonal angle, the metal tip will automatically come out and wrap around the lead to protect it.
