15 cm is quite large. Do not enter the work clothes pen. I can not fit it. I am using the marking pencil that I am using now so much that it will be so big with a difference of 12.5 mm 2.5 mm. The noise when knocking from the knock-type sharpening that I am currently using is great. I do not mind if I do not mind. Core cutting cap is well cut. I think that this function is superior compared with the core cutting cap made by another company.
