This was my second project before building the sterling silver mod and it served as the prototype. The body is a copper tube while the top and bottom is made of brass. Every part is also handmade but it's much more hard to make than the silver one since soldering copper and bronze is much more difficult. I've decided not to use it anymore since I am now using my sterling silver mod. Also copper tends to smell when it is exposed to sweat and I have sweaty hands.
