There are so many possibilities with these little pieces of metal, you'll want to buy lots. Originally meant to be novelty rings in the 1970s or 1980s, they might still be used as novelty jewelry. You might also use one as a ring base and glue or solder other neato stuff to them.
Each is adjustable, so, it will fit most fingers.
But you might really love to flatten them out and use them in your other altered art and collage projects or as other types of jewelry.
We are showing two rings - one from the side and one from the front. The top/front measures about 1/2 inch and it is easy to pull the two sides apart to adjust the size or to flatten the metal.
