This is a cooler bag from the Anpanman Traffic Safety Caravan. It has a gusset and is cute(^^) I stored it in its original packaging, but I took it out because the outer bag deteriorated. The contents are clean, but please understand that this is a long-term storage item before purchasing.✩.*˚ Size: Approximately 16cm (height) Approximately 29cm (width) Approximately 9cm (gusset) I often use cooler bags because they are consumables, but my child has grown up and no longer uses Anpanman, so I hope someone who likes it will use it♡
