Full description

If you (or the self confessed geek in your life) ever needs to know "pi" to fifty decimal places... or you just want to increase your intellectual standing, this set of four handmade pinback buttons adds both a reference point and unusual colour to any outfit or item.

Attractive graphic designs feature the mathemetical symbols for "pi", "e", the golden ratio, and the square root of two, surrounded by the decimal expansion to far more places than you'll ever need.

Each badge is 1 inch (2.54 cm) in diameter, and the set is mounted and presented in a clear cellophane bag.

Items are packed in a padded envelope, and sent by first class Royal Mail.

Original designs, handmade by me, Mike at Badge the Badger.
