Thick wires
Size: 4/0AWG, Color: 10ft Black + 10ft Red
Heavy duty for my solar set up. These wires are thick. I've never used such thick wires for anything. Now I know why they're so expensive. There was some weight to these wire too. The diameter is larger than a dime. These are some serious wire.

Monster cable
Size: 4/0AWG, Color: 3ft Black + 3ft Red
Well I now know what 4/0 or 0000 cable is. Huge but very easy to handle or bend to shape.
