I’m not entirely sure how these work, but I think you’re supposed to dampen them and then put them on you to cool you down in hot weather? They’re made of polyester and I don’t think they’ve ever been used.
Pick up between 9am and 5pm on a Tuesday, Wednesday, Friday, or Saturday. Location is 3 minutes' walk from West Croydon Station. Priority given to people who are nearby, and who tell me in their first message exactly when (date and time) they want to come.
