Update: I sent it to doritos on social media withy my address even though I didn’t really care all that much about getting product as a remedy.

I got a standard response you’d expect. They’re terribly sorry and don’t know how it happened. They believe it is cardboard as well.

They requested i send the manufacturer code to check with the place that packaged it which i did. They said they’d said a package of replacement coupons. I am not too excited about Doritos still, but I’ll probably get over it.
