## Description

Finest writing instruments/ stationary products from Japan, Mechanical Pencil lead, Ain STEIN, 0.5mm x 60mm, 3B x 40 leads

Review: Best Mechanical Pencil Lead - Mechanical pencil leads in a hardness of 4B is difficult to find in general. The AIN Stein leads are high quality 4B leads. They work well, they feed well, and they leave a dark line with little to no pressure. When you're dealing with mechanical pencils in the 0.5mm range it can be easy to break leads. 4B leads allow you to write with a much softer touch and leave the same darkness of line; this is kind of counterintuitive for some. The notion of a softer lead just breaking easier isn't necessarily always the case because less overall pressure is required to write. I've pretty much switched out all of my mechanical pencils (and I have a LOT) to 4B or 3B. I just wish the 4B grade was offered for the 0.3mm leads (only 2B is available). Lastly, just remember, 4B is (6) grades of lead softer than 2H (the most common type of pencil lead). I strongly recommend any mechanical pencil lover to try these AIN Stein leads out. You won't regret it.
Review: Nice dark leads - Smooth and dark leads. Better than just hb leads. Pack of 40, will last a while. Use them for regular note taking, and these work great. give it a try, you will love it.
