A color line up appearance newly classic to mechanical pencil "Dell guard" that a core is not broken 0.5mm!
I add a honeycomb pattern for schoolboys, a square pattern for girl students, the design which I was particular about in detail which I put a transcription technology for each to brisk standard model 0.5mm.
The latest mechanical pencil which solved "core jamming" "to break a core" that the Dell guard uses a mechanical pencil and feels to be dissatisfiedly.
By new development Dell guard system, I follow a core from every direction. 今までのシャープペンでは、先端に必要以上の筆圧が加わると芯を支えている先金がシャープ芯を支えきれず折れてしまっていた。 I do not already compromise even if I write it densely even if I write it fast by solving this problem by Dell guard system. Therefore I can write it all the time.
I prevent core jamming by filling the gap by the deployment of the spacer. 今までのシャープペンでは、落下などの外部からの衝撃によりシャープメカ内部で芯が折れたり芯がずれることで、芯づまりが起きていた。 I solve this problem by a spacer and therefore am not clogged up anymore.
In the most important scene including the everyday learning and test, I can show the best performance.
A sharp core: 0.5
A spare eraser: G type
[Dell guard] the mechanical pencil that a core is not broken
[the Dell guard system deployment] follow a core from every direction
[lengthwise direction] upper part spring misses absorption /2: core in pressure of the pen in the upper direction, and 1 prevents buckling up
[slant direction] the absorption /2: tip jumps out of pressure of the pen, and lower part spring guards a core 1
[※ attention] When I knock more than four times from the state that a core is not over and write it, I may compromise
