Meet postal specifications for bulk mailings. Very stretchy very little breakage. Beat the heck out the the ones the post office used to provide to bulk mailers!
I deliver newspapers and I decided to start buying rubberbands instead of using newspaper bags and I've used other brands and so far these have proven to be the best! They're strong and don't break easily. I can wrap them a couple of times around the newspapers without worry of them snapping and hitting someone or something. I will definitly continue to purchase these!
