Pi Cufflinks

Here are the must-wear cufflinks for March 14th - Pi Day. The day when the world of mathematics competes to see how much they know about the world’s best-known irrational number. Made of indestructible stainless steel, in the form of the Greek letter π, these cufflinks mark you as a mathematician, engineer, physicist or general all-round geek.  But the flowing lines also make very good-looking cufflinks for the rest of us.
