Inkless pen writes forever

When you finally become a celebrity (unless you already are one), this pen will mean you'll never have an excuse not to give out your autograph. Worse, you'll never have an excuse not to write a check when your career goes south.

That's because this writing instrument doesn't need ink to work--that's right, Skippy. Instead, it has a metal-alloy tip that can write on most types of paper and will never smudge or be erased, according to Spluch. That could come in especially handy when your bar napkins get wet.
