Title: Does exactly what it's meant to do - protect things in mailing. Made in USA.
Review: These bubble envelopes work exactly as they are supposed to - protect things while mailing. I don't know how well the seal holds, as it is my habit to put a piece of tape over the flap proactively. Each envelope is 1/3 or less the cost of buying it elsewhere (Target, etc.). With 50 envelopes, they'll be around awhile, but for such a great deal it is worth it. I have used them to mail: plastic packages of food, books, and clothes.
