We switched over to these after the other report covers became a bit too expensive for our needs. We normally put about 20-30 sheets in them at a time and usually it is just the right amount for these to handle. The one thing I do not like about these is that the plastic slide grip that you slip on constantly seems to snag the plastic if you angle it at all. The slide gripper ends up covering it up most of the time but it can be a real hassle to get these lined up correctly without ripping the plastic. Overall they get the job done even if they are a bit more flimsy then I like. They're decent for mass amounts of less then 50 page documents you need for your presentations or other projects.
They are your typical resume covers or for important papers to give someone. I'd prefer if they had them in other colors besides white possibly blue or black bu I bought the bulk pack to save a little money still expensive. Relatively easy to use Align paper first then put in sleeve then align paper again. Start placing hard plastic in the middle and then slide up once on from middle to top then slide to the bottom. Doesn't have to be perfect cause binder clip hides the papers a little.
This was a great products for the money. I was looking for an inexpensive way to give some structure to a 25 page project. These covers kept the pages together and protected them. I liked the fact that I could create my owner cover page and that it showed through the clear plastic covers. I mail the reports that are put into these covers and with them being so light weight the covers did not add much in additional weight to the package which is very important. Very pleased with this product and would recommend to a friend.
We have used this product for about 3 years and have been very happy with it to date. Some times it can be hard to keep the papers straight when the report has a lot of pages to it. Over all this is a great product for the value.
