Green jerry cans.
Jerry cans are robust containers, typically made of metal or heavy-duty polyethylene, used for storing and transporting liquids, especially fuels like petrol and diesel.
They are known for their distinctive rectangular shape, often with three handles, a hinged lid, and a design that facilitates stacking.
Originally developed in Germany for military use, the design was later adopted by various nations and industries worldwide due to its durability and practicality.
