It's made with the paper stock weight that I like best and the liner is classic! There are other cheaper choices at other stores but this is the old school security envelope I have used for years.
I needed 100 envelopes for a community project and so I grabbed this box. I didn't even realize these were EasyClose but what a blessing....I did not have to lick or sponge wet these envelopes to close. it was so easy and quick and I'd recommend these 100%.
