Can't find this braided water supply line any ideas?

I bought two shampoo sinks off craigslist, I need a 3/4 braided water supply line but can't find one to match the existing. Does anyone know what this is called and where I can get one?

Specific to the faucet as far as I know. It would thread I to the body
