Regarding the authenticity guarantee, I stopped using it after a genuine item I purchased at a department store was deemed unsuitable and returned. It seems the companies doing the authenticity checks on Mercari are not very knowledgeable about brand-name items (^^) If you are concerned, please refrain from purchasing. Purchased at a department store in Tokyo. I received it as a gift, so I don't have the receipt. I bought too many down jackets this season, so this one didn't get used. I'm hesitant to sell it, so I might suddenly remove the listing. It wasn't listed on the official site, so I've included product details from another website (in photos 15-20). Hooded cropped down jacket, white. - Color: White - Design: Hooded, zip closure - Style: Cropped length - Pockets: Front pockets - Material: Down jacket Thank you for looking.
