These items were packaged with Ichiban Shibori beer. Set of two. They can be used as a cooler box by putting ice water and cans inside. Great for outdoor activities and camping! They are made of thick, sturdy paper. Also, it seems to be constructed in a way that prevents water leakage even when filled with ice water. *Please use within 3 hours to avoid water leakage or damage, according to the warning. *Box only. As shown in the photos, they will be neatly folded for shipping. #IchibanShibori #CoolerBox #Camping #Outdoor
