Is it possible to resell a ticket? How?

If you purchased a PASS (3-day or 1-day) but can no longer attend the festival, you are allowed to resell it, even if it is non-transferable.
Please note, however: Reselling tickets for more than their face value is prohibited by law.

There is no official platform for reselling MozHell tickets.

Avoid selling on public social media platforms. Offer the ticket to a friend, acquaintance, or within local metal community groups.
