These protectors are not archival safe, but might be handy for low budget school or home projects that will have a short life.
I bought these to use for sorting address information for an organization I belong to. I knew that I was buying a lower quality product, but don’t accidentally pick these up if you are looking for something good.
They hold standard 8.5 x11 inch pages, load from the top, and are 3-hole punched for normal binders.
The sheets are clear, but with a glossy finish, so they glare when you try to read through them. This also makes them more slippery than some other sheet protectors. They will pick up and hold ink transfer from copied documents.
The binding edge seems strong enough; I haven’t had any of the holes tear out.
They are useful for temporary storage like sorting recipes or correspondence or bills, but don’t keep things in them that you want to preserve long term. Always look for the words “archival safe” on the package if you want to protect papers.
