- DelGuard Type-Lx
For those who are particular about function and design. Chic black with matte paint from clips to grips.
It protects the core from breaking even from the strongest writing pressure at any angle during writing.
When a strong writing pressure is applied vertically to the paper surface, the spring built into the shaft allows the core to escape upward and prevent it from breaking.
(It may break if you knock it 4 times or more from the state where the core is not out and if you write using a color core or a dark core of 3B or more.)
- Sharp core diameter 0.3mm
