I bought some poly mailers from an Etsy store and that’s how USPS delivered to me. It was absolutely not the seller fault, and I was thinking if this is also happening to the orders that I’m shipping! I have never received any complaints about it but I wanted to maybe prevent this from happening. I sell baby bibs and bummies and they would probably be damaged if something like that happens. I was thinking about maybe start lining the poly mailer with a cardstock could be helpful.. any ideas for preventing the order to be damaged?
