I have been using these folders for many years. They not only protect but do not stick to the inserts. The inserts are very clear. I have used more expensive sheets but these are the best for anybody's money.
I have used 400 of these and they are sturdy and easy to use. Papers slip in easily. I just ordered 400 more. The real test will be seeing how well they hold up. The price was reasonable and with free shipping I couldn’t go wrong.
These sheet protectors are clear and the plastic is sturdy enough so it doesn’t tear when you are loading them and using them in a binder. The holes are prepunched for standard binders.
I use them to protect my patterns that I get on line to put in notebooks they are taken out and used the protectors are great. I like this weight as they are easy to use.
