Hello ☺︎ Thank you for viewing. Now back in stock. I made a lunch bag. The lining uses a mesh-type thermal insulation fabric. Because it's both cooling and warming, it can be used all year round. Interfacing is used, so it's sturdy. The inside uses a washable cooling/warming sheet. We recommend washing it in a net. (Do not tumble dry) 【Size】 Height 18.5cm (Excluding the drawstring part) Width 30cm Bottom width 20cm (The shortest part of the bottom) Gusset 10cm Since this is a handmade item, it's not perfect, but I make each one with care. Thank you for your understanding. #handmade #lunchbag #lunchbag #bag #coolingwarming #cooling Pattern/Design: Other
