MEGAMI PROJECT rings are crafted using the most advanced technology in the jewelry industry.
*When purchasing, we recommend that you measure the size of the finger you will be wearing the ring on beforehand using a ring gauge or similar.
*Although this varies from person to person, if your finger is swollen due to the time of day you take the measurement or your physical condition, the size may fluctuate by about 0.5 sizes.
Please determine your ring size based on the condition of your finger.
Also, wider designs may feel a bit cramped, so we recommend choosing a size slightly larger (1 to 2 sizes).
