What's the preferred container for prints?
I'd like to use the "Monkey method" but I don't have a laminator

I normally print direct into a jar, so I'll be printing on foil to send (unless I can find some Tyvek tomorrow) and I don't know what to put the prints into after I've taken them. I'd normally use little ziplock bags, but since you say "no baggies" I don't know what to use.
