I am always creating presentations at my job, and a white ring binder is often my preferred method of presentation. The Business Source .5-Inch Round Ring View Binder has everything I need:• Sturdy construction• A dependable mechanism• Clear insert sleeves on the front, back, and side• Pockets on the inside• Good clearance for hole-punched paper when the rings are closed• Wide enough to accommodate divider pages with tabsThis Business Source offering us up to the task. I feel the white PVC looks cleaner when white letter size sheets are used in the outer view windows. The rings open with a firm 'click' and snap solidly closed. The slim 5" depth is good for presentations that don't run more than 100 sheets. I tend to use a thicker paper stock, so around 60-80 sheet would likely be the maximum I'd use. Extra sheets and cover letters can easily be slipped into the inside pockets. It works well if you have only 30 too, whereas a 1" binder would be awkward with that sort of reduced content. The size also makes it easier to pack more to bring along with you trade shows or meetings, and helps with shipping costs.The one issue I have is the current price of this product. It's on the high side for a single unit, so look for sales or bulk deals. Perhaps I am spoiled from normally getting products such as this in quantity from office supply stores. Otherwise, I'm quite happy with the Business Source .5-Inch Round Ring View Binder.~ Kort
