PORTER Heat - Bundle Sale. These Heat bags are incredibly durable. They have some dirt and scratches from use, but are still usable. I'm selling them because I don't use them anymore. I'm selling them as a bundle at a low price to save on shipping costs. I think it's a great deal. Please purchase with the understanding of no returns, no exchanges, and no cancellations (3N). If you'd like to buy individual items, please leave a comment!
