40m of stranded wire all 10 standard DCC colours (4m of each). This wire is a similar thickness that which comes with DCC decoders, meaning it is nice and flexible and particularly useful for many modelling applications such as hard wiring decoders or lighting. It comes as a ribbon cable but is easily separated. The colours are red, orange, yellow, green, blue, purple, white, black, brown and grey wire which are the standard colours used on all DCC decoders. The second picture shows it next to a dcc plug for scale.
