Thickness of the chain: 1.2 mm
The length shown is the shortest chain. The longer chain is 0.5cm longer for a nice pendant.
How do I choose my chain length? Measure the distance from piercing to piercing. You can either do this with a tape measure or a string and mark the beginning of one piercing and the second piercing. Measure the distance between the marks with a ruler while you have the string laid flat.
