It seems the ice melts slowly, lasting about a week. It has been stored at home, so there are some minor scratches, but there are no problems with use. It has only been used once, when I went camping before. Please check the photos for the condition. This is the "55QT Cooler Box" from Peace Park. This cooler box has a design that blends in with camping, with attention to detail. The vertical design allows you to stand up 2L plastic bottles and wine bottles, making it easy to take them out. It comes with a removable drink holder, a divider that can also be used as a cutting board, and a basket that can be hooked onto the opening. There are two drink holders on the top. The durable body made by rotational molding and the walls, which are about 5cm thick with foamed polyurethane injected without gaps, provide high cooling power. If you fill the cooler box with ice, it will take about 7 days for the ice to melt in a room environment of around 25 degrees Celsius. I am also selling a Robens tent, so would you like to consider it together? 55QT beige cooler box, excellent durability and cooling performance. Price: Around ¥38000 - Brand: peace park - Size: 55QT [approx. 52L] - Color: Beige Thank you for viewing.
