Masks used in Sleep No More in Shanghai and Seoul. These were used in the show, so please purchase only if you understand that they are used items. Unlike the NY masks, these have a mechanism to secure the mask to the head. This is a set of two, but individual sales are also possible. Due to shipping costs, individual masks will be relisted for 1,500 yen each. Multiple masks are available, and you can purchase additional masks for +1,000 yen each. Please inquire via comments. They will be disinfected, protected from water damage, and shipped.
