Good Quality
Size: 2 Colors each 10FT, Style: 22AWG
Good quality wire. Doesn't fail and break after only a few bends or twists like most cheap wire. The silicone insulator is great for flexibility in tight spaces like guitar electronics cavities. I'm constantly trying out new part and pickups and found that some cheaper wires were often failing due to being moved around all the time.

Great wire

I needed a flexible durable wire to fix an old model train. It worked perfect. Wire is generally wire. If you require all the special features of this wire it will meet all your needs
