This piece is built using the rosette weave with anodized aluminum rings. They contain no nickel, lead or zinc and so are hypoallergenic. The standard length of our anklet is 10" but if you need it to be a different length just leave me a note and we will make sure it fits you just right. If you choose the trimmed in secondary color option please be sure to leave a note in the "special instructions to seller" section to let me know what other colors to use.
