About This Design

Math geek Pi symbol, blue on black Coaster

Math geek Pi symbol, blue on black Coaster

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.

Bright and colorful! The printing is nice and crisp. True to color as seen on the webpage. The cork backing is well placed and there are no loose edges. I love this sandstone coaster! I would recommend this product for gifts, stocking stuffers, or for yourself!
