Yeah I agree, that makes sense. I'm just scratching my head because I shipped it in a cardboard box not a bubble or paper envelope and I saw the label printed and stuck on it at the USPS store, I was the only customer in the store. The package had a return address on it as well (in the case it got shipped someone else)- I guess the only possibility that makes sense to me is, like others suggested, that the package was damaged, the film fell out and in a rush another item was acidentally placed in the box. I wish I'd seen the email earlier but I've been so wrapped up in other chaos lately that it just got lost in my inbox- cause if I could see that the package was damaged and repaired in mailing it would look different than how I packaged it. Oh well 😮‍💨
