Derailer cables, front and rear (pair)
Stainless steel, good.
One short for the front derailleur; one long for the rear; exact lengths vary. To be safe, consider these good only for small bikes or downtube shifters or both only as long enough for the front derailer. But if you have high and comfy handlebars, bar end shifters or a big bike, then these may not be long enough.
