The Styrofoam Cube In This Letter Serves A Bureaucratic Purpose

When Chris opened a letter from the Indiana Election Division, he was curious why in the world there would be a small Styrofoam cube inside the envelope. Luckily for everyone involved, there was an explanation.

Written on a strip of paper packed with the letter was the following declaration:

The Styrofoam cube enclosed in this envelope is being included by the sender to meet a United States Postal Service regulation. This regulation requires a first class letter or flat using the Delivery or Signature Confirmation service to become a parcel and that it “is in a box or, if not in a box, is more than 3/4 of an inch thick at its thickest point.” The cube has no other purpose and may be disposed of upon opening this correspondence.
