Green aluminum-coated eco-bag with illustrations, foldable. - Color: Green - Strap Color: Brown - Inner Material: Aluminum coating - Foldable: Yes - Design: With illustrations Thank you for viewing. This is a ZAQ eco-bag I received as part of a campaign or something. The inside is covered with aluminum material, so I think it can keep things cold or warm. Also, it's a convenient foldable type. There are some slight frays, but it doesn't hinder use. Please refrain from purchasing if you are concerned. I've only used it a few times, but I will clean it simply with disinfectant wipes before shipping. Also, if you would like to know the detailed size, please feel free to ask. #ecobag #ZAQ #coolerbag #thermalbag #foldableecobag
