Hello ☺︎ Thank you for viewing. I made a lunch bag. I used interfacing only on the handles, so it's sturdy. The lining uses silver mesh type thermal insulation fabric. Since it's thermal insulation, it can be used all year round. The inside uses a washable thermal insulation sheet. We recommend washing it in a net. (Do not tumble dry) Lunch bag 【Size】 Height 16cm 　　　　　　　　　　Width 28cm 　　　　　　　　　　Depth 10cm Bottom width 17.5cm Handle 26cm Since it is a handmade item, it may not be perfect, but I make each one with care. Thank you for your understanding. "Textile designed by COLORFUL CANDY STYLE" #handmade #lunchbag #entrance #enrollment #fieldtrip #thermalinsulation #lunchbag Type: Lunch bag/Lunch bag
