[Diagonal direction] 1: Lower spring absorbs writing pressure / 2: Tip extends to guard the lead. [Caution] If you write after knocking more than 4 times from a state where no lead is extended, it may break. The premium version of DelGuard, which prevents lead breakage and clogging, combining function and design, the "DelGuard Type-Lx," is now available in 0.3mm! Writes finely and beautifully. Yet, it doesn't break. DelGuard is the latest mechanical pencil that solves the "lead breakage" and "lead clogging" frustrations experienced when using a mechanical pencil. The newly developed DelGuard system protects the lead from all directions. With conventional mechanical pencils, when excessive writing pressure is applied to the tip, the metal tip supporting the lead cannot hold it, causing it to break. The DelGuard system solves this problem, so whether you write fast or dark, it won't break anymore. Therefore, you can keep writing. The inclusion of a spacer fills gaps, preventing lead clogging. With conventional mechanical pencils, lead breakage or misalignment within the mechanical mechanism due to external impacts such as drops would cause lead clogging. The spacer solves this problem, so it won't clog anymore. Achieve your best performance in crucial moments like daily studies and tests.
