More companies should do this kind of advertisement.

I have a box of 120 Blackwing pencils of all types. They look nice, expensive, but a bad tool.

They are not suitable for fine drawing (too waxy and soft) - those are either STAEDTLER, FaberCastell, or Tombow (Japanese brand).

The fancy tip eraser is also not very useful. The metal around it is so soft, it can't hold any pressure. Also extremely not child friendly, as the small metal part inside just fells out.

Tombow Mono - de-facto standard eraser.
