Cut sections of wood dowel to the right length: then they can be cooked / soaked in flavored water. Recall "cinnamon toothpicks?" Like that but bigger and we have an array of awesome artificial flavors now.

If its the finish texture and the weight that's appealing, perhaps you could find a flashlight or "stash case" jewelry item that could serve the purpose. Somewhere, someone has a "drug safe" that look very much like an AA battery but the top unscrews and its a hollow chamber inside.

If you think its the flavor of copper; then they sell copper pipe in a variety of sizes; you can cut lengths of that and have no worries. I can't think of a battery that actually shows copper on the outside tho.
