Remington Industries 22PTFESTRBLA100 22 AWG Gauge Stranded Hook Up Wire, 100 feet Length, Black, 0.0253" Diameter, PTFE, 600 Volts

Amazing quality. Compared to generic Chinese PTFE wire, this one is a joy to work with.Update after a month: wire is performing remarkably. I put it under constant stress and so far no signs of deterioration. I keep it in a hot environment and it is subject to repeated bends throughout the day. Will post an update after a year.
