These are the most elastic rubber bands around. What a great stretch. They really hold true if you pull them and let them go. Got long hair? Buy a bag of these rubber bands. It will be good for the economy.... The bag has a great ziploc seal to keep out any unwanted dust air sunlight bugs even boogers. Just don't leave these rubber bands in direct sunlight for weeks at a time as they can become brittle. Put on a copy of the rubber band band and dance your tail off to the Staples Economy rubber band!!!!!
