This is a set of 4 SK-II Facial Treatment Masks. I received one mask (not individually packaged) in December 2025 and three masks in January 2026 at an SK-II counter. Shipping will be via Yu-Packet Post Mini. I have stored them with care, but there may be minor scratches or stains. Please purchase only if you understand that these have been stored at home. Returns are not accepted. I am also selling on other sites, so your order may be canceled depending on the timing of your purchase. Thank you for your understanding. ※ Unless otherwise specified, all items I am selling were purchased at authorized retailers (including online) or received as samples. ※ Due to work, I am often unable to respond during the weekdays. I will do my best to respond as quickly as possible, but please understand that I may not be able to reply to comments or purchases until the evening. Also, I have set the shipping time to 2-3 days just in case, but I usually ship the next day. It depends on the timing, so if you are in a hurry, please ask before purchasing.
