This piece is built using a combination of the helm weave and the Japanese 12-2 with larger gauge anodized aluminum rings so it is a chunkier statement piece. These also use the EDPM rubber rings to give it the stretch. The anodized aluminum contains no nickel, lead or zinc and the rubber contains no latex 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.
