What it does

  • Holds your pens and pencils upright so your desk stays neat and tidy
  • Built from the digits of Pi, so you remember math facts while you work
  • Unique desktop accent that sparks conversation and shows your love of math
  • Works as a small vase too, so you get extra use from one piece

Keep your pens where you can grab them and make your desk smarter at the same time. This Pi Penholder puts the digits of the famous number right on your workspace. Every time you reach for a pen, you will see those numbers and remember a little more about Pi.

The tower design stacks the digits of Pi into a shape that holds your writing tools. It sits flat on your desk and does not take up much space. You can use it as a vase for small flowers too, so it earns its spot on your shelf. The clean, simple look fits any office or study room.
