Beadalon Stringing Wire .015
Beadalon bead stringing wire is composed of tiny wires twisted together and nylon coated. The number of tiny wires, also known as strands, determines the flexibility of the wire. These spools are 7 strand so they are flexible but will retain their shape. These wires cannot be knotted so you crimp the ends.
Bright is the least visible and is the most popular for that reason. It basically doesn't show up very much. The other colours are used when you want the wire to show and be a design element.
.015" is the most common - good for most projects. If you need help choosing, message me. Happy to help you !
