From Wikipedia
A rubber band is a loop of rubber, usually ring or oval shaped, and commonly used to hold multiple objects together. The rubber band was patented in England on March 17, 1845, by Stephen Perry. They were originally used to hold papers and envelopes. Most rubber bands are manufactured out of natural rubber as well as for latex free rubber bands or, especially at larger sizes, a synthetic elastomer, and are sold in a variety of sizes.
