This is a neck lifting mask from KISS MUSES, the first cosmetic brand from Korea. I have only used one sheet. The official website is: https://en.kissmuses.com/ - Brand: KISS MUSES - Product Name: NECK LIFTING MASK - Official Price: $29.00 per box This is about ¥4,500 in Japanese yen, so I think it's a bargain. Thank you for looking.
