I was in Rio for the final show of the Celebration Tour. I was able to get one of these rare but official tour chapsticks. You will see in the flyer (also included) this was an exclusive item released through Riofarma, a limited item where there were massive queues to get this unique item! 

This has never been opened, but as you will see on the flyer, the chapstick tube also has the tour logo on it.
