Thank you for viewing. I used this for about six months after purchase. I would like to give it away since I no longer use it. I think you can still use it! Product Specifications Material: Outer layer: PVC mesh cloth material Middle layer: Thick Mirra mat Inner layer: Stain-resistant aluminum foil Size: 35*26*45cm Accessories: Adjustable T-shaped siding Storage pockets on both sides The large side pocket can store wallets, smartphones, etc. The mesh pocket can store water bottles, notebooks, etc. Divided design There are two adjustable dividers, which divide the internal space into three sections, allowing you to carry multiple items. Not only does it effectively cool and keep warm, but it also makes effective use of the internal space. It can be used not only for delivery but also by general users. It can be used in various situations such as picnics, hiking, and barbecues. Thank you very much.
