I am using the sheet protectors for a large project now. Every time I pick one up I am surprised and pleased with the thickness. The top is easy to open to slide the paper in. I have used cheaper protectors before that it was difficult to open the top of the sleeve and get the paper in without a struggle. These protectors are a breeze to use. The only thing troublesome is they are so slippery. If you have a pile the pages may slide all over. I would love these in matte format.
I was surprise on how durable these sheet protectors turned out. the papers are easy to pull in and out of the sheet protectors. Not too thick and not too thin. Very flexible when turning the pages and they slide easily when turning the page.
