2 Robbins Conductive Thread 65ft/20m for Arduino Lilypad with Needle ThreaderSilber Fiber: What sets this thread apart from the other conductive thread that we carry is the fact that its actually spun from silver fiber making it incredibly smooth and without the loose hairs seen on other Robbins. Super Low Resistance & Ultra High Condutive Performance: It means the resistance is as low as about 60 80( m). Suitable for hand or machine sewing (as a bobbin thread). 33ft 10m for a Robboin: This is 10 meters of smooth conductive
