Color: Black系 Condition: No stains or tears Porte Monnaie Jour - Monogram Eclipse / Black / Coin Case / M63536 / L-shaped zipper (2320563353305) The serial number is not printed on the product. I checked and it seems to be the type with an RFID chip embedded. When you scan the product with a dedicated app, the chip information will appear, but I don't know how to read it because it seems to be brand confidential information. *Please check the last photo. A coin case with a design that features a ruthenium-colored zipper that stands out against the masculine Monogram Eclipse canvas. It is highly functional, with an L-shaped zipper that makes it easy to take out the contents, and a compact size that fits neatly into a small bag.
