These are nice and thick which is what I needed. They are holding manuals for appliances electronics etc..Also cords and little wrenches that came with furniture. This is why I needed heavy duty ones so they would not tear when placed in binders. These keep everything organized neatly and easy to find.
I thought I was ordering clearer more rigid sheet protectors which I plan to use in making face shields to help protect supermarket workers and others against spread of covid-19. Since I planned something other than their intended use (page-protection) I cannot fault the description in the online catalog; but I wish that there were some way to distinguish the more rigid clearer sheets from the more flexible "cloudier" ones (nonreflective). Thank you.
