The PRICE of these sheet protectors is great; however the USEFULNESS is non-existent. The protectors are sealed on ALL FOUR SIDES leaving no opening to insert the sheets you wish to protect. And because they are not an item which is carried in-store (it's similar but it is NOT the same product) the store personnel cringe when they see them come in for a refund or exchange since it means money out of their pockets. I've spoken with other merchants in my area (after the fact of course) who report they've all had the same problems with this product. They indicate they either cut them open with shears or an Xacto knife or -- when they get frustrated enough -- they exchange them at the "local" store (15 miles away) for a higher quality product which costs more but (like me) they are unhappy at being forced to make a long drive to do so and (also like me) are not especially happy when they arrive. No wonder the store manager (and/or his staff) gets up in arms! Why doesn't someone in "Quality Assurance" at the distributor level address this problem?
