We couldn't get 10x13 at the big stores and looked on Amazon. It didn't disappoint. The feel a little bit lighter weight but they seem to work fine. We are stuffing a decent amount of papers and receipts and they are holding up. I will buy again soon since we need 1000 plus every tax season.

Great weight of paper, and I liked the glue AND the clasp. Very sturdy and well made.

These envelopes are excellent for keeping papers, photos and other files. They have plenty of room due to the fact that they are 10 x 13“ and they are very sturdy.
