pentel is known to produce great mechanical pencils. this one is really nice, strong design and good rubber grip. can put good pressure on the lead and it do not usually break easily. nice for marking, drawing and filling omr sheets. a perfect writing tool cons may be that the metal tip is not retractable(but it helps to prevent lead breaking on sudden pressure) and that the rubber grip may become loose after long use. but still it is simlpy good. love pentel , definitely japanese perfection ...
