Very hard on the paper and light lines. It is biased towards an H grade lead, I
prefer leads that feel hard and won't break but that will write softly and with
dark lines. My personal favorite are the Uni Nano Dia leads.
Standard cheap case with only 12 leads. Very expensive for what it provides. I
really like Lamy products (Those were my introduction to the world of pens), but
these leads disappointed me.
