This is a Chanel pearl brooch. The size is approximately 4 cm in height and 5.7 cm in width. I purchased it at a domestic Chanel boutique several years ago. As it's a design that is synonymous with Chanel, I didn't intend to sell it, so I discarded the box. The last photo shows the engraving. Also, please rest assured that everything I'm selling was purchased by me at authorized boutiques. Please check the condition of the item in the photos. Feel free to ask any questions you may have.
