I purchased these Staples Gummed Security Tinted #10 Business Envelopes because they were the only privacy business envelopes you carried that had the single window. They are not of the same quality that you used to sell. The are made of paper that is so thin I am concerned that they might not make it through the mail to their destination. I will look elsewhere for this product in future.
The gummed envelopes are much better (securely seal) than the ones where you peel off the strip to close-they do not seal well - are not secure. Will always buy the gummed envelopes in the future-highly recommend them.
