Parker Liquid Lead Pencil 这玩意现在还有么？

The Liquid Lead Pencil concept was as simple as combining ballpoint technology that Parker had mastered with the Jotter with a new "liquid lead-pencil graphite" paste in the refill. In essence, the new "pencil" was a graphite lead ballpoint pen.

Interestingly, Parker designed the new Liquid Lead Pencil as a non-retractable, explaining that the "lead" is "self-retracting," and that, "It actually withdraws from the writing point when not in use." How this is achieved is not explained, other than to assure prospective buyers that the pencil will not leak or seep, making it safe to insert in a pocket without fearing a stain. The graphite "ink" formulation in the refill is apparently less likely to wick out than ballpoint ink, and in practical use it appears to be essentially true. Parker never changed the design in the seven years of production, lending credibility to the claim. Reliable, non-leaking ballpoints were still a fairly new concept although public acceptance was very high.
