Personally I don’t like that they have Staples printed on them. I make Personal cookbooks and it makes them look tacky. Will have to use another product.
I expected heavy weight sheet protectors and clear. They are flimsy and glary protectors. I wouldn't recommend this if you need a clear heavier protector.
These are awful -- front & back are stuck together very time-consuming to open. Then an 8.5x11 sheet barely fits into the sleeve. The medium weight ones are much easier/more efficient to use.
