This size is my favorite. It has good stretch to it already so when I'm putting around a large stack of papers it won't make them curl up in the middle. It's not so thin that it breaks as soon as you use it. Also it can be used again & again without losing it's shape. I work in a print shop & it's always the size I go to first. It's a great product at a great price.
My company manages all of the parking for the University of Michigan. Since we use various parking permits of varying amounts all torn off stubs and bound together with rubber bands. I have tried many types of rubber bands for this purpose since we need fairly strong rubbers bands because of the need to keep the tickets in order and to be used over and over again. Of course we also use them for bank deposits and to bind stubs to return to the university. I would recommend the Economy #32 Rubber Bands for this purpose. That do not break easily and are sold at Staples at a reasonable price.
HI We have purchased 20 + bags this year. Out of them 3 bags were very brittle or broke when stretched. I would say that heat was the problem either in shipping or storage. Being in Phoenix and Arizona heat is a problem especially with rubber bands.
This is the most convienient way I have found to purchase our rubber bands. We print 350 bulletins each week for our services at Church and we use the bands to keep them neat.
