UK based designer Gemma Holt makes jewellery based on pencils & bic pens. Currently, these babies are not yet available in shops, as Emma is a fresh-faced post-graduate from the RCA (Royal College of Arts). But you can ask her for a copy very nicely by contacting her on her site.
According to her college CV, you can also:
"Ask me about measurements, roller coasters, market stalls, the golden ratio, airplanes, the art of making do, appropriation and more."
Good to know!
