do elf bars have metal in them

*Elf nods, intrigued by the question. Elf grabs another bar from the batch and holds it up.* This is actually a very interesting question. These bars don't have any metal in them, at least not in the traditional sense. They're made from a special alloy of aluminum and titanium, which gives them a unique strength and durability. So they're not just strong, but they're also lightweight and highly conductive. The metal is actually embedded in the structure of the bars, not just as an outer coating.
