There's nothing fancy-shmancy about these envelopes but they do a good job for shipping cds and other oddly shaped documents. I do appreciate that they don't tear easily and are not flimsy however these are plain envelopes and do not have any sort of padding so I wouldn't suggest putting anything more fragile than a compact disc in them to ship. They seal nicely but I wind up putting a little bit of tape across the metal tab for extra security. All in all this package is a good price for the amount of product.
These envelopes are practical for both business home and school usage. Business for small packets of documents home for mailing sorting and filing. School for fund raisers sorting and mailers.
