The one thing you never seem to have when it's time to sign something is also the one thing you'll never be without after today -- 'cause this pen lasts a lifetime ... no kiddin'!

Allow us to introduce the Forever Pininfarina Cambiano Inkless Pen -- and, as the name indicates ... this puppy carries ZERO mess or risks of stains as part of its built-in make-up.

It's true ... these hand-crafted, wooden pens are, in fact, "inkless," which may seem like an oxymoron -- but trust us, it's the real deal. Now ... how the heck does that work???

Welp, it's got this patented metal alloy tip that writes a distinct line similar in look to a pencil, yet with all the permanence of ink ... but without lead or graphite. Still confused? Yeah, it sounds like sorcery, but it's actually legit science -- the marks from this pen are achieved by oxidation created through contact between tip and paper. Mind blown, right?

Here's what you need to remember about our pen here ... it never runs dry, never stalls on ink, and never needs that handy-dandy shake we give disposable pens to get them started.

If you consider how many full-blown packs of BICs you've blown through (and lost) over the years, a small one-time price of $64.99 for this ever-after tool is pennies in the long run.
