- Model match
- Japan ranking listing: KOSE face mask; Taiwan product page: 7-sheet pack; spec option "Sake Lees Mask"The Japan listing's jp=440 corresponds to Maison KOSE's Clear Turn Bihada Shokunin Sake Mask (Sake Lees Mask), 7-Sheet Pack, ¥440 (tax included) (source: Maison KOSE's official site, maison.kose.co.jp, product page). momo/PChome/DA-KOKU Drugstore all showed no results for the "Bihada Shokunin" series (only @cosme.net.tw and the Cosmed website mention this series being sold in Taiwan, without a public price). A Google search instead found the same series' 7-sheet-pack item at Yahoo Shopping Mall's "3 Beauty Cosmetics" store, whose spec menu includes a "Sake Lees Mask" option, with the volume (7 sheets) and series (Bihada Shokunin) matching. Root re-verification: Yahoo Shopping Mall (3 Beauty Cosmetics) product page re-check: Kose Japan Bihada Shokunin Mask, 7-Sheet Pack, NT$109, with a Sake Lees style option available; the source ranking itself specifies the sake-lees version (listing id kose-sake-kasu-mask), and the sheet count of 7 matches the Japan listing. All styles on the page show 0 stock, recorded as-is. Yahoo Shopping Mall is a Taiwan platform, not within the Shopee/Rakuten prohibited range.
