Pilot Neox high-purity graphite leads are specially formulated to resist breaking while also being darker and smoother than other leads.
How to open the container:
1. Peel off and discard the long silver sticker covering the top of the lead container.
2. Flip the plastic tab that was under the sticker up to a vertical position. This exposes an internal plastic cover with a hole in it.
3. Tilt the container upside-down and shake it gently until lead comes out.
