NOBOLT Dedicated Socks - Set of 2 These are dedicated socks for NOBOLT (inside Marinoa City) in Fukuoka City. A set of these socks must be purchased for 440 yen when using NOBOLT. I used them once for 2 hours a year ago. I am selling them because I have no plans to use them in the future. Sizes: M: 21-24cm x 1 S: 17-21cm x 1 There are small pills, but I wore them gently, so there is little staining and they are in a clean condition. They are still usable! Home cleaned.
