Pi Tie Bar

6 items left

Ancient, mysterious, elusive, and beautiful -- pi symbolizes not only a number, but also the ongoing quest of science and math to approximate the universe just a little better. Wear a stylish and sophisticated piece of the eternal puzzle with this hand-stamped tie bar displaying pi to 10 decimal places.

Available in aluminum or bronze, it is sturdy enough to last a lifetime. (Note that hand-stamped lettering varies a little, so yours will be charmingly unique.)

Perfect for:

  • Mathematicians or math aficionados
  • Engineers
  • Architects
  • Rational and irrational people alike
  • Anyone cool enough to celebrate Pi Day

Love the tie pin for my math teacher nephew!

Searched for something cool to buy for our nephew, who recently transitioned to teaching from a corporate career. Found the Pi tie pin, and hope he wears it well to work sometimes. Well made and a fun gift! Arrived on time and nicely boxed.
