this is a easy fun way you can etch any bare metal! I've used this on cups and tools. you could etch anything metal! jewelry, cups, signs, tools you name it! it only take a 9volt battery, salt, water, some wires to connect the batteries to your material, some cotton, and a sticker, cricket vinyl, or just tape( something to use as a stencil for your etch)
