I got this at the Uber Eats booth at the 2023 Pride Parade. A reflective keychain. A super rare item distributed only to delivery people who came to the event venue in Yoyogi. I think you can attach it to the basket or box on the back of your bicycle or motorcycle. Of course, you can also attach it to your bag. Wearing it will make you look like an old-timer.
