We bought these because it was really our only choice. This assortment or much more expensive same size ones. Only Staples brand was available. These seem to stretch well and it is nice the bag can be reclosed but only time will tell if they last. Often rubber bands tend to dry out and then break when trying to use them. That will be the test. Hopefully keeping them in a the resealable bag will extend their useful life which would be great and then 5 stars.
