Black Formal 9-piece Set IGIN VON (Silk)

I am listing this item on behalf of a relative, so I am not very familiar with this brand. However, after researching online, I found that suits handled by Igin Co., Ltd. are described as high-end formal wear.
Indeed, the fabric feels very pleasant to the touch.

The care label indicates it is a silk product, so I believe it is quite a high-quality item.
