The First Class 6300 by Eberhard Faber is an oversized pencil, whose name—sans hyphen—suggests they were made for young students. I don’t remember the first time I was ever given a pencil at school, but I do remember using thick ones (the crayons were thick, too). Everything about this pencil just seems sized-up from standard measurements, including its lead:
The polish is reminiscent of the late Microtomic line. It writes very nicely and holds its point a long time; the lead may be closer to No. 1 than HB. Either way, the First Class is a first-class pencil.
