Thank you for viewing! This is a handmade insulated pouch. It's made with an insulated sheet on the inside. It can be washed, so you can keep it clean. It can be used to carry neck coolers, snacks, etc. when you go out on a hot day. Zipper: 20cm Size: Approximately 20cm wide x 24cm long This is a handmade item, so it's not perfect, but I've pre-washed the fabric, ironed it, and applied a thin interfacing to make it carefully. *It may be folded and changed to Yu-Packet Post Mini for shipping.
