There is a flat rate tyevek envelope, but you have to order them from the post office online.. They are great!!! you pay $6, and can stuff as much as you can get in the, They are extremely strong.. and they are a FLAT RATE!!!!. You have to be careful when you order them, as there are other tyevek envelopes that look like them, but are not flat rate. Please check the website. I have used them for a while, and others have used them from the board in the swaps that we are doing..

You are correct that it is NOT - but it's worthwhile using it at times. Sometimes it's a much better 'deal' than the medium flat rate boxes.
