Thank you for viewing. This is a set of 4 Pyrex PEANUTS Halloween food storage containers. After purchase, I took them out of the box and stored them, so I no longer have the box. Three are unused. One has had the film removed, and I'm not sure if it was used once or not used at all, but I don't think there are any stains. I haven't used them, so I'm putting them up for sale.
