Sakatsu-Ultra-Fine Wire-Outer Diameter Approx. 0-38mm-Non-Scale-4512 Sakatsu Co. Material: Non-Scale\nThis is likely the thinnest wire commercially available.\nWhile capable of conducting electricity, its extreme thinness limits it to low-voltage, low-current applications such as LEDs.\n\nIt is also perfectly sized for representing plug wires in 1/24 scale model cars. Former name: Plug Cord\nWhen used as an electrical wire, it is rated for 100mA or less and 4V or less. \n5-core 0.07mm wire with
