I am on my third box with no complaints. Also there is no need for me to use a hole punch to my important documents. If needed I can use a "Post It" on the outside with additional information which also saves marking up my document.
Having used many boxes of these for record-keeping of church records estate records and organization of household business in all uses this product was superior.
I have used these sheet protectors in binders for Kindergarten RTI groups. There is a cardstock sheet of letters or pictures in each one and the students have to highlight or write the letter for each page. The students write on the sheet protector with dry wipe markers as highlighters. They are very easy to see through so students can check their work and very easy to clean off. There is no residue from the markers and the sheet protectors stay clear for multiple uses throughout the year.
I have used this products to compile all photos and paper work from an old industry in our village. This way the items can be viewed by any interested party and they are not damaged. They fit in notebooks nicely no hole problems.
