These are some of the smaller rocks I brought back from Maine. I’ve (cleaned them thoroughly and) glued a magnet to each of them. That means they stick in those metal tins! The incense boxes are plastic, but I’m using them because they’re a bit taller and can thus accommodate the two rocks that are a bit taller.
