This is a product from Renaud Pellegrino, a famous French leather goods brand. Renaud Pellegrino, after working as a dedicated designer for Saint Laurent, became independent and made a name for himself in the fashion world with his unique sensibility and worldview. I purchased it at Wako in Ginza and used it a few times, keeping it carefully stored. I bought it for under 200,000 yen. There are some small, inconspicuous scratches if you look closely, but I think it's in beautiful condition. The gold hardware is expandable, and the design is elaborate, with four plates overlapping to close like a key, giving it a gorgeous feel. Recommended for those who like [implied: luxury brands, unique designs, etc.]. This item is also for sale on other apps, so please comment before purchasing.
