**Item:** The Glowing Digits of Pi Stickers. This listing is for all 4 stickers in the set. We've taken our super small printing and applied it to Glow In The Dark Stickers. The Glowing Digits of Pi Stickers each display the first 15,502 digits of Pi. The digits are printed at under 2pt in size but are crisp and readable. And...the background glows in the dark so you can read the digits in the dark!

It's a really cool effect. Shine a flashlight at the stickers for 30 seconds, turn off the lights and you can ready the Pi digits using the green glow. The glow servers as a back light, similar to a transparency being viewed with a projector. Using only the glow, the digits, though darker, are even readable in the center color image area.

**Magnifier / Loupe:** Unless you have a strong magnifying glass or loupe with at least 5x-10x power or more, we suggest you add one to your order. Depending on availability, we may provide a different magnifier than shown in the photos but it will have the same specs as what you've chosen, or better. The magnifiers we provide are a great combination of value and power and help with reading the content comfortably.

We offera 2.5x/6x credit card size magnifier with The Glowing Digits of Pi Stickers. It's flat and fits perfectly with the stickers. The stickers - and frankly, anything that glows in the dark - are still fun without the magnifier. But this is Pi after all and being able to comfortably read the digits adds to the experience.

**Awesome Pi Facts:**

- Pi is the ratio of a circle’s circumference to its diameter.
- Pi is an irrational number, so it has an infinite number of decimal digits without a pattern or order.
- The Pi symbol Π was first introduced by William Jones in 1706.
