We like to make sure that the documents we mail to our clients arrive safe and in good condition. These are strong and durable so that the documents don't get damaged in the mail. They stay closed and are also water resistant. A little expensive but we haven't found any cheaper for the quality and they last us a long time. Would recommend for a small office!
As a small accounting firm we have used this product to mail client information packages via US Postal Service for many years. One hundred percent satisfied with their strength and durability. Clients appreciate the appearance and safety of their information.
We have to mail out K1's to partners every year. I was glad to find large envelopes made of Tyvek. I felt this would help protect the documents from damage. I was also glad that "First Class" was already printed on the envelopes. Even better they were peel and stick!
I use these envelopes to mail out the new stock certificates and the New Stockholder letter. I send them via Certified Mail with Return Receipt. I love that they have First Class printed on them as well as the First Class green markings around the edges of the envelopes. Also the Certified Mail forms adhere well to the Tyvek. I feel the documents inside are well protected not only from tearing but from moisture. These Tyvek envelopes are all that I use for the purpose of getting the new stock certificates and any accompanying documents to the new shareholders.
These are used to send individual tax returns sales tax and payroll tax returns. They cost more than any other envelope but they look real classy when they arrive. Because they are very difficult to open and it is obvious if they have been tampered with I'm happy that they arrive at their destination with a look that security is a top issue with my firm.
