Coolant Pack Case for Bento Boxes - Handmade This is a case for attaching coolant packs to bento boxes during the hot season. * W-gauze is used for the inner fabric, so it absorbs water droplets and dries quickly♪ * Since it has a rubber band, I think it can be used for bento boxes of different shapes. * Size: Approximately 12cm long x 9cm wide It's the size that fits the coolant packs that come with cakes, etc. This is a handmade item. I make them carefully, but there may be some distortion or imperfections, so please refrain from purchasing if you are looking for perfection. Thank you for viewing! #CoolantPack #CoolantPackCaseForBentoBoxes #Sayaka_handmade
