eneral information:

Jewelry wire is a steel cable which is coated with plastic. It is often used for threading pearls because jewelry wire is very strong, extends neither the time nor discoloured and it can be closed easily with crimp beads.
The number of legs indicates how many individual strands are wrapped. The more strands the softer and more flexible is the jewelry wire.

This jewelry wire with 7 strands is a standard product which is used for threading medium to large beads. As long as it allows the holes of the beads it can be used for smaller beads but it may looks a bit stiff. For smaller beads we recomment a jewelry wire with more strands.
