Mechanical pencil lead might seem like it’s the same from brand to brand, but the graphites are actually quite varied. Some brands use better lead than others and even sell high-end aftermarket lead separately from their pencils.

Think of mechanical pencil lead like a pen refill: the one that is included with your pencil might be fine, but it isn’t the only one you can use and it probably isn’t the best one available!

Best Mechanical Pencil Lead

Pencil leads are, generally speaking, harder to differentiate than pen fills.

Pentel Ain Stein

If you want premium or upgrade pencil lead, you can’t really beat Pentel Ain Stein. It’s strong, consistent, and clearly it was thoughtfully made with a better writing experience in mind. It gives good feedback when writing and the packaging is easy to operate, keeping lead spills to a minimum.

Uni Nano Dia Blended

The other unquestionably top option for pencil graphite is Uni Nano Dia Blended with its “nano diamonds” blended in. This is a strong, consistent lead that’s a pleasure to write with. This is a great all-round lead that, assuming you pick the appropriate lead hardness, is great for note taking, drawing, mathematics, and all sorts of other tasks.
