Quality, heat resistant silicone wire for my heating coil wine bottle cutting project. I didn’t need very much, but provided me the best price and option. No regrets.

Loong jumper test cables.
Size: silicone wire red 25ft and black 25ft, Color: Red and Black
Over-kill makes nice tools. This is good tinned fine stranded wire with quality silicone insulation. Five-star stuff, without buying some expensive large quantity minimum from a high-end wire manufacturer.
