These have a bright pink copper tone and come to you freshly tumbled, free of burrs. They are ready for you to weave with them.

Why are the True Aspect Ratio (TAR) and the Anticipated Aspect Ratio (AAR) different? Because the AAR is calculated on the Mandrel Size and the advertised Gauge Size - these both vary in the real world. The TAR is based on the actual accurate measurements of the jump ring diameter and wire thickness.
