A fabulous piece that is very flexible, light to wear and has a high reflect.  One sphere is filled with Aston Martin Valkyrie swarf (shavings) used to make various engine/gear box components.  It is steel and has a great texture/light reflect.  The other side has brass swarf also from the Aston Martin Valkyrie.  These are set on twisted, stainless steel wire.  A great gift for any motorsport or car lover.
