"Dead-Soft" wire is extremely malleable and can be bent easily into a myriad of shapes. It does not hold its shape in stress situations, such as clasps. In reference to wire gauge size numbers, the larger the number, the smaller the diameter of the wire. Example: 24 gauge wire is smaller in diameter than 18 gauge wire.
