These mailers are top quality and can hold so many things! They are exactly what I need for business use. The quality is better than other mailers I have seen advertised.
Only thing I do just to be extra careful is apply tape to the closed seal. I do this anytime I use this type of mailer but it isn’t required. This is a solid item.
The mailer was light weight however the packaging materials were sturdy. The envelope opening was wide and allowed for easy insertion of documents and a small gift box I was mailing. I sent 12 mailers and not one recipient had a problem with the contents being bent or the box being damaged.
