All listed sizes are READY to ship using Amazon fulfillment. I handcraft these penny rings in small batches using a genuine 95% copper U.S. penny. Different size rings develop slightly different shapes (smaller sizes will be thicker, larger sizes will have a thinner band size). Each ring develops its own character during the forging process, making each one unique; no two rings are exactly alike. The outside band of your ring will read "United States of America" and "One Cent". The inside of the band will read "In God we Trust". I do NOT apply any type of sealer to the rings. The copper will be in direct contact with your skin (some people prefer this). Copper, for some people, will turn skin green or gray. To prevent this, you can coat the ring with clear fingernail polish or jewelry sealer. Due to making the rings in small batches, and sending to Amazon to fulfill, some ring sizes may be unavailable or out of stock. If your size is not showing, or out of stock, check back soon.
