This is a rare BDSS product only available at specialty shops. I finally found and bought it, but the size didn't fit. I purchased it for the retail price of 16,500 yen. I am not reselling for profit, but I will add the Mercari commission to the retail price. It's more expensive than retail and shipped with the buyer paying the shipping costs, so it's hard to find. If you really want it, please go ahead! I'd like to keep it even if it doesn't sell, so I'm not considering any discounts.
