Anti-Breaking Lead System! A guide pipe protects the entire length of the lead, which enables you to write without extending the lead out of the guide pipe. Since the pipe has rounded edges, it will not scratch the paper.
Click once to advance the pipe with the lead.
Adjust length of the lead to the same length as the pipe.
The pipe will protect the lead from breaking while you write, draw and doodle!
Available in 0.5mm lead, refill with standard 0.5mm leads.
