He does it well
Better than digital notepads, the blackboard remains a safe bet for monitoring work (graphic designer and photographer). It's always on and doesn't consume anything. So I took this pencil because it is more practical. It does its job, it covers well and is resistant to erasure and less messy than chalk. It takes water to erase it, and that's what I was looking for. Very white, fine writing. Very good.
The priming at the beginning is a bit long but that is normal for this type of product.
The chalkboard is more ecological than whiteboards and their markers which dry out and never work, and get dirty quickly... Chalk is the most ecological, but this white pencil seems to me a good compromise between ecology and productivity.
Yeah, all that for a pencil.
