Fluorescent yellow reflective sash, unused. Reflects car headlights and improves safety at night. Helps increase visibility from cars when walking at night, such as for jogging, cycling, patrolling, or dog walking. There is no size listed in the description, but it appears to be folded in half, so the overall length is likely over 90cm. Although unused, this item has been stored at home for a long time, so we appreciate your understanding. It will be folded in half from the condition shown in the photos and shipped via either Yu-Yu Mercari Mail or Raku-Raku Mercari Mail.
