Rainbow rubber stretchy chainmaille bracelets made with black EPDM rubber rings and rainbow of colored anodized aluminum rings. This is my own unique pattern, it is not as stretchy as some other patterns but still rolls over the hand nicely with no clasp, due to the stretchy nature the sizing is approximate.
