About This Design
Math geek Pi symbol, blue on black Key Ring
It you would like to get the design where the first 10,000 numbers of Pi are clearly visible, I also have that design, with a few variations, on my store. Pi is an irrational number, that is calculated by dividing the circumference of a circle by its diameter. Nothing seems so simple, yet Pi is one of the most fascinating, non-repeating numbers (at least for now) ever. Show of your love for mathematics with this design, full of geeky attitude.

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
