Thank you for viewing! This is a handmade mimosa-patterned insulated pouch. It's made with an insulated sheet on the inside. It can also be washed, so you can keep it clean. I think it can be used to carry neck coolers or snacks when you go out on a hot day. Zipper: 20cm Size: Approximately 20cm wide x 24cm long Since this is a handmade item, it is not perfect, but it has been pre-washed, ironed, and has a thin interlining. * I think it's a color that got mixed in during the fabric manufacturing process, but a light blue line can be seen in one place (image 6). I don't use a blue pen at home when making things, so I think it's from the fabric manufacturing process. Please understand. * It may be folded and changed to Yu-Packet Post mini when shipped.
