The envelopes are great - they don't tear and they stay shut even after a few years! My local store didn't carry them I had to order online which I should have checked before going to the store. But they came quickly so it wasn't a problem but I will check on other items first online. Don't forget labels for them. Some pens will not write on them very easily so you might need an address label.
We have always used these Tyvek envelopes to ship items. Knock on wood but we have never had a complaint that an item was lost or damaged. Its a great product. Definitley recommend them.
I sell crocheted items and was looking for a "light weight" but sturdy way to ship my my customer's orders and these work perfectly! The 10" x 13" size is roomy enough to hold my creations and sturdy enough to ship them at minimal cost (which I know we can all appreciate). With prior envelopes used (not Tyvek) I would also tape the flap to assure a quality seal. With these I no longer feel the need to do so as the QuickStrip seal is surprisingly strong; thus saving me money on tape. If you're thinking of buying these but are hesitant because of the price don't be....... They are well worth the money. You will not be disappointed!
We like to use the Tyvek envelopes when mailing out of state since they are so much sturdier that the paper envelopes. The box having 100 envelopes has not been an option at the office supply store in town so for them to be a better price and a larger quantity was a pleasant surprise. Also if you don't have a Staples Reward Card/Account get one!! Free shipping on a smaller order (like this one-just a box of envelopes and some mechanical pencils!) is another good reason to shop Staples.
