This is a poly tank cover case from TOOLS (Tools). (20-liter poly tank cover) The poly tank is sold separately. It is not included. I purchased it and used it once, but after that, I didn't use it and it was stored in a closet at home. It is in good condition, but please understand that it is a used item. Size: Width 260 x Depth 380 x Height 350mm Material: PEVA (Polyethylene Vinyl Acetate) Product Details: The 100% waterproof PEVA inner lining allows it to be used as a cooler box. It's a stylish poly tank cover that can also hold water directly. It uses a material with excellent heat retention, so you can comfortably change clothes with warm water from the insulated poly tank after a cold winter swim! The large side mesh pocket is designed specifically for the poly tank case to always maintain ventilation, making it excellent for storing surf accessories such as leashes and wax. Because it is waterproof, you can use it as a simple cooler box by putting in ice packs and ice during leisure activities. It also has an easy-to-carry handle, so you can also put in lunch boxes with ice packs and go out to outdoor events with your children, such as sports days. It can be used not only as a 20-liter poly tank cover but also in a wide range of situations such as camping, outdoor activities, surfing, swimming at the beach, and BBQs.
