These are perfect for closing my Interactive Notebooks in my math class. I just hole punch the back cover of a composition book approximately 1" to 1.5" in from the upper right corner. I then loop the large rubber band trough the hole and then wrap the band around the covers. I also like how they come in different colors - this gives my students a color choice for their composition book. The package comes with 24 large bands. I wish it was a little cheaper - because i need to buy in quantity. I have over 210 students this year.
These are great for keeping larger 8-1/2 x 11 papers binders and books together. I wish there was a slightly smaller size available (like 5" x 1/8") but they only offer much smaller stiffer sizes at the store. THese rubber bands stretch pretty far - like the ones we used to shoot in drafting rooms!
My printer lid had torn hinges. Rather than spend the cost to have the printer fixed or purchase a new printer I simply used these large rubber bands to hold the cover in place so I could continue printing and scanning.
