Xoa GrayInteresting. Soe one of the things I noticed about my Pentel Orenz Nero is that at .5mm it made very light lines. To where it was actually a little hard to read. So I went down to B2 lead which basically fixed the problem.
Apparently I wasn't the only one that had this issue. As this year Pentel changed the leads that come with their Orenz line mechanical pencils from HB to B. It's not as soft / dark as the leads I'm using, but it's a step in the right direction.
