Resists breaking and never needs sharpening * 0.5mm, fine lines * B is a soft lead that produces a dark line density * Easy to read and smooth writing feel * Fits all 0.5mm mechanical pencils
I've used Pentel lead refills since my first mechanical pencil. They're definitely stronger than the generic stuff. As long as I don't lose this box, I don't think I'll need to buy refills for many years.I used to have the HB variety. I thought I'd try B to see how much darker it is. I haven't had any breaking yet with my new Graphgear 500 and I can't really tell if it's darker.Great lead, great price. Do yourself a favor and don't buy junk lead.
