KOH-I-NOOR Fine Graphite Leads for 0.3mm Diameter 60mm HB Mechanical Pencil

Just rubbish. I cannot believe how bad these are compared to others I've purchased. The problem is how easily they break while you're writing. I use mine for maths/writing and I threw mine out - they are unusable.

I can't rate these as the were not in the package. Koh hi noor is a good brand so they will no doubt be high quality.I've contacted Amazon about this, but no response.

Likes - at least I can fit to one of my pencils.Dislikes - continually breaking when in use - very poor, should be more durable!!!

I would not recommend this. They are so fargile and break easily.

Just the right hardness without being brittle. Smooth to write with and rarely breaks. Better quality than Staedtler at a lower price

Great graphite if you have a light hand! , works in all 0.3mm pencils

arrived in time and good product

The price is fantastic and works great on my pentel.
