About This Design
Pi Day PiDay Chalkboard Education Key Ring
It’s not irrational to know your Pi. Teacher posted the most significant digits in the circle shape of Pi along with the symbol in chalk. Celebrate Pi Day every March 14, which is also the birthday of Albert Einstein. Do you suppose this is just a coincidence or is it the secret power of math? Pi is one of the most important numbers in mathematics, so memorise at least 3.14 or 3.14159 before you dig into your pi day pie on PiDay.

Product quality is great, art work is perfect.
Would highly recommend.
Fast turn around, I was surprised they arrived so quickly, as I had a fairly large order. Perfect, centred and exactly what I wanted
