I love them! I'm an avid reader and normally read hardcover books or my Kindle. However I occasionally read paperbacks. To keep them from bending I use the rubber bands to keep them closed. The paperbacks are large books.
I have been using these over sized rubber bands for years and they are great for so many things. When you have a lot of papers to put together a regular rubber bands won't do the trick; if you have anything that requires something to hold it these rubber bands are your ticket. You will find many things you can use these for; I always keep them around for I never know what use I will put them to but I always find one or two or three or hundreds.
These were not the large Rubber Bands that I bought a few years ago at Staples. The older bands were made of the regular rubber that all other bands are made from and were 2-3 inches longer. I bought these colored bands this time but am not happy with them.
