The set includes rainbow binder covers! I also have this rainbow pattern on other products like the sub tub, sub plans, and classroom set bundle. I recommend printing these items on card stock so they are more durable. Laminating would also be a good option if you are not sliding it into a binder plastic cover! These are standard printer paper size so they also would work well in dividers organizing one binder!The font I used was "Hello Big Deal". To be able to create in this font go to dafont.c
