Saint Clare was a good friend of Saint Francis of Assisi and began the female order was Francis' counterpart. She is often shown with the Eucharist because of a story that says Attila the Hun was coming with his horde to take over the convent when Clare ran and got the monstrance and warded him off with Jesus Himself. 

The same image is on both sides.

All of our pendants and ornaments are made with lead free solder and glass. Great on a chain or bracelet. We offer a ball chain elsewhere in our shop. 

If you put the charm/medal on a key chain, it may get broken if not treated kindly. It is glass. If you want one for a key chain, we can custom make your medium charm/medal with a thicker glass for $3. Small charm/medals don't need thicker glass, but either way, they need to be on a chain before you add them to your key ring.
