I haven't brought any rubber bands lately because I get plenty of them from the postman wrapped around the mail. But these rubber bands seem very weak. A lot of them break as soon as you try to use them. I suspect they are a cheap quality and not meant to last much longer than the one time they come wrapped around the mail. I will buy some rubber bands from Staples and see if they are better. If there are different grades, I'll get the best.
