Friendship bracelets at concerts?

Helloooo :)

I am visiting the concert in Munich this Summer. I’ve been preparing some friendship bracelets with songnames/lyrics/names of the members etc. But I was wondering if that’s actually something that people do at CP concerts, since I actually only really ever noticed it at Harry Styles / Taylor Swifts shows.

It’s not even about trading, but I just want to gift them to some fans.
