These envelopes are rock-solid. I have used them for years without issue. I tried another manufacturer once, but ended up going back to Quality Park because they always hold-up in the mail. Somehow, the box always seems to be broken when I receive these, but that has never impacted the envelopes themselves. The price on all envelopes seems to have gone up a lot in the recent year, but they are still a good value in comparison to others.

Excellent product. Solid paper stock. I will definitely purchase again in the future. Highly recommended.
