I purchase these is large qunatities and they are used over and over again without showing signs of weakness. They don't break very easy and they don't get stretched out and lose their shape. I also have not seen where they dry rot and break due to poor quality rubber. We use these for a few pieces of mail to banding together larger bundles of mail and find the rubber bands to be very reliable. This size works well for bundles of mail without being too strong or too weak. Sometimes it is difficult to find the right size that does't roll the mail. These work great for us.
Periodically we need to purchase rubber bands for the office. The one pound package provides a great value. The quality of the product is good so there is no need to shop elsewhere.
These are good rubber bands. Thicker than just your normal bands but not so heavy that they will not stretch. We stretched these around a pumpkin and they did not break. LOTS of Rubber bands in this bag.
I use rubber bands every single day at the office. The # 19 rubber bands are my favorite size for many different reasons! They are the perfect size for file folders and stacks of paper because they are plyable enough to hold everything together without making the stack or folders "roll" they keep everything nice and neat and flat. They also work really well if you need to secure smaller items because they can be doubled or trippled over without difficulty! I have and will continue to order the staples brand as well they are very good quality.
