I was a bit disappointed in the thickness of these. They were thin and I thought about returning them but didn’t because I needed them for my students. I cover drawing sheets for them to copy or trace which will protect them. They’re ok tor this but not for a professional binder.
I have used these page protectors in the past and they work perfectly for my home office organization. They are sturdy and protect documents well. I like the size and the design of this product. I would recommend.
