Wristband collection is organised and managed entirely by the event organiser, so we aren't able to answer specific questions about it directly.
The best place to look for wristband collection information is the event listing on Fatsoma, the organiser's social media pages, or any emails they've sent out ahead of the event.
If you can't find what you're looking for, reaching out to the event organiser directly is your quickest route to an answer.
