Thank you for looking. This is a mobile arm bag, an official merchandise item from the Tokyo Marathon 2023. Since it's difficult to get into the Tokyo Marathon, I purchased this at the official shop within the EXPO venue as a souvenir. It's a pouch that can be worn on your arm for jogging, walking, cycling, and more. ■Although it is new and unused, I opened it for photography purposes for this listing. Because the product name sticker and the "THANK YOU" sticker indicating purchase were attached to the opening of the outer bag, the sticker tore slightly (see photo 8). The product itself has no issues, but please only purchase if you understand this. ■Color: Black ■Size ・Clear vinyl part dimensions: Height 16cm, Width 8cm ・Slot for smartphone: Width 7.5cm ■Material: Polyester ■Has a dedicated hole for earphone cords. It is Velcro type, so the attachment position can be adjusted. ■Shipping will be waterproofed and sent via anonymous delivery using Yu-Packet Post or Nekoposu. #TokyoMarathon #OfficialMerchandise #Pouch #ArmPouch #Armband #SmartphoneCase #RunningPouch #ArmPouchHolder #Marathon #Running #Jogging #Walking #Outdoor #Stroll
