If you like shells, these are great. The size works with just about any piece. It's a BEAD, not a hanging charm, and there is substance to them because they're not one-sided. I like to scatter them in a necklace or bracelet, and I've used these in between small pieces of chain (with nautical charms attached to the chain), to make an unusual charm bracelet. Make sure to purchase a few because you'll want to use more than one!
