This piece is constructed using the 3x3 weave and can be ordered in the traditional style with a lobster clasp or as a continuous stretch anklet with no clasp to deal with. We make ours with anodized aluminum rings and if it is a stretch version then we also use EDPM rubber. The aluminum contains no nickel, lead or zinc and the rubber has no latex so they are hypoallergenic. The standard length of our anklets is 10" but if you need it at a different length to fit properly just leave me a note and we will make it happen. If you order a piece trimmed in a secondary color please leave me a note in the "special instructions to seller" telling with the other colors you would like.
