The priority boxes are, but not these envelopes. In fact, I didn't see any quite like these at the post office. This will be my way of mailing from now on. I like to save a buck where I can.



FYI: I added Tape to the self sticking tape. (Just in case)
I was able to get 11 full yards of fabric inside and could probable have gotten one or two more.


You may need to check at the post office again. I retired a year ago and the tyvek priority envelopes were free then. I had several customers that used them for e-bay and I supplied them with both boxes and tyvek envelopes. Sometimes they are out of stock and/or have limited supplies of the Tyvek envelopes. You can order them delivered for free too. Important to understand - priority rates apply, to the free ones. The plain ones are sold and the rates for mailing can be less. --- I agree with extra tape. Sometimes the adhesive provided is not enough, especially when the package is stuffed.
