These rubber bands don't stretch enough and they break easily. After trying an other similar product I now go out of my way to purchase them because the performance is so much better. They stretch and don't break. Your rubber bands stretch to a point and just don't go any further. At this point they usually snap and break. I buy a more than rubber bands for business. But the rubber bands are used for binding up product that I have to return to the home warehouse. If I have to go out of my way to get a product that performs well I'll usually get other supplies there as well paper tonier envelopes pens and tape.
