Thank you for viewing! (^o^)! This is a mask featuring the 211 series (Kuha 210-3002). Brand new and unopened. It functions as a mask, of course, and is also washable. ^_^ This mask was previously sold exclusively at a store in Omiya Station. It is no longer sold and is extremely rare. I am also listing this item elsewhere. If it sells elsewhere first, such as at the same time or overnight, I will have to cancel the order. Thank you for your understanding. 211 series, train, and railway fans, please consider! #mask #211series #Kuha210-3002 #211seriesmask #railwaymask #trainmask
