I used these rubber bands to make diaper cakes. They were the only ones that I could find that were big enough for the bottom layer of diapers. I liked that they were flexible but not stiff. They were a bit pricey as far as rubber bands go but since they were the only ones I could find this size I had no choice.
The size and strenth of Staples large rubber bands are the advantages. They don't break while stretching them over a large quantity of papers or materials. I get very frustrated when I need one and the supply is gone. Smaller rubber bands do not stretch as far break and snap and often hit me in the process!
