These binders are among the better quality binders I have used in my business. They are easy to open and close when you only have one hand available. The binder also has a front slote for storage. The outside front cover has a clear slot for customization.
This Staples brand product is just as good as Avery with the D binder rings and clear outside cover that you can slide in a cover sheet. They had a lot of colors to choose from. It was an added incentive that I bought with the old binder trade-in. I have always found that the Staples brand is just as good if not better than the name brands and of course save a lot of money. Watch the specials weekly and subscribe to the daily deals and you can save even more. Look for when filler paper is on special to fill the binder.
My husband and I do a lot of traveling and when we come home I place my copied photos in special pages and keep them in heavy duty binders. We especially like the D ring binders as they hold more pages and they are easy to open. Recently when Staples had their special sale on binders they offered new ones at a great price - one for each old binder turned in. We had several old ones really unusable but they were taken in exchange for four brand new ones. We like the ones that have a clear view pocket on the front of the binder as I put a special sheet there about the country that was visited. The spine of the binder also has a clear pocket where the name of the country can be placed - easily seen when the binders are on the shelf.
I use a lot of these three ring binders. I do family history and use the staples binders to save the research I find for each family and for things I do with the Boy Scouts Of America. The binders are very heavy duty and with the pocket on the front and the spine it helps to put a nice cover and spine label. They are less expensive than Avery and just as nice. You can get different colors that will help keep things sorted. The different sizes make it nice when you have a lot to store on one subject. Best price well made.
