These sheet protectors appear to be more durable and protective of their contents as compared to standard or economy sheet protectors. Also like the fact that they provide UV protections so the contents should not yellow as can occur with cheaper sheet protectors if they are left open and exposed to sunlight. The only negative I found was the initial loading of contents since there was a minor amount of static discharge. Also since they are thicker than economy versions it takes a little longer to fill them but I believe the long term durability more the makes up for the initial inconvenience.
