No you read it right. It is a supplier of a bunch of stuff, and I linked to plastic sheets. You would have to cut it to whatever shape you want. It is not a pre-made pack frame. Sorry, that is what I thought you were looking for. If you want a pre-made plastic pack frame, you either call the manufacturer of one, or buy one and take the pack bag off. I could be wrong, but I am not aware of a place to just buy a plastic pack frame.
I've taken a vow of poverty. To annoy me, send money.
