Since the pen body is strong, since it is a metal body, there is nothing like cracking the former cheap resin body, the chip of the skee is the same, because it is necessary to write also on the surface of the rusted steel material, it often breaks the resin made by force It is cheap to us if we last long.
This is good! By making it all metallic, there is no break due to insufficient strength of the body which was a weak point of the pencil type! Also, the thinness of the core and the degree of sharpening are best for precision scribing. Moreover, it is saved that you can use the core made of Shiwa that has accumulated until now, repeating replacement! I tried to increase the strength by winding a vinyl tape round and round in plastic, but those who experienced sighing still broke! This is it if you buy!
