Avery Heavy Duty View Binders is the only binder I use for our customer informational binders. We send out hundreds of them to our customers every year. The "one touch" is wonderful when you are fillling binders with index tabs. It is so easy to open and close with one touch. These binders take a beating at our dealer locations and we are constantly adding material to them. So nothing short of a heavy duty binder will do. It wouldn't reflect well on us if the binder our customer goes through looking at our product is falling apart! Highly recommend to those who want a binder that closes correctly everytime, can stand a beating, and has crystal clear viewing windows for our photo covers!
