Our Stairway-to-Heaven Anklets are constructed of anodized aluminum rings. They contain no lead or nickel and are hypoallergenic. They can be ordered in a wide variety of colors or you can contact us to do custom colors. They are made using the traditional Rhino Snorting Draino chainmail weave. 10" is the standard length of these pieces but if you need a different size just let us know.
