This is a two-pack of Gunze boxer briefs for summer. I bought these this summer but didn't use them. They might be good for the gym or exercise even in winter, as they are cool. There are some color variations. Please be sure to check my profile. These are items stored at home and offered by an amateur seller, so they are not perfect. Please refrain from purchasing if you are concerned. I may have overlooked some loose threads or stains, but please understand this before purchasing. #BoxerBriefs #BoxerPants #Men'sInnerwear #Men'sUnderwear #Gunze #GUNZE #QuickDryPants #AntibacterialPants #OdorControlPants Size...M Color...Blue系 (Blue-based)
