I thought these would look cool on my bass, turned out I like shiny chrome better. These are satin chrome, but they look more like grey to me. 2 are still wrapped, I took one out to try and did not like it. My loss=your gain. They are very light, I would guess aluminum since they are Hipshot made. These retail for 14 dollars each, will sell the set for 30 shipped or best offer, paypal accepted.
thanks
