The size of the charm is 9 mm x 10 mm You will also receive instructions on how to add or take out the charms and links. These medical alert charms will bring attention to paramedics about your specific medical condition. Italian charms are always interchangeable. You can add more charms and links and you can take them out and switch them around.
I have many more allergy charms. Contact me with what you need. I will add them to this collection.
I can add these in my bracelet for you if you order the charms and bracelet at the same time.
