Astage Denver Surf Cooler Box This is an item to be used as a small item storage compartment in the hole on the right side, which is intended as a fish insertion opening. This is a handmade item by an amateur using a 3D printer, so there may be layer lines and burrs. If you are concerned, please process it yourself or refrain from purchasing. The material is PLA. The heat resistance is about 60°C, so it may deform if left in a hot car for a long time. It is also weak against impact, so please insert it gradually when installing. We try our best to prevent it, but please understand that the contents may move between the front and back spaces when opening and closing the cooler box, depending on the size of the items you put in. Please consider purchasing this item, understanding the characteristics of PLA filament and that it is a handmade item by an amateur. Currently, we are selling items made of PETG, a material with stronger heat and weather resistance, separately. Although the price will be higher, please consider those as well.
