www.MeteoriteGuitarPicks.com: Plectrums from outer space! These picks are made from 4.5 billion* year old meteorites. At prices in the $135 region you'll need to remember to hang on to them and not chuck them into the audience at the end of a gig.
(* That word "billion" always confuses me. Is that the real mathematically-correct 1,000,000,000,000 or the modern Americanised 1,000,000,000, i.e. a thousand-million?)
