Inquiry about the Uniber Open Package Freeroll ticket

[AeroStreams]

Hi there,

Does anyone know what the Unibet Open Package Freeroll ticket can enter you into? I have one from the rakeback I earned a few months ago. I cant see any tournaments I can use it in. I see there are some unibet open online freerolls but I cant use it in that. Is this an old ticket I need converting?

Here is a screenshot of the ticket.

Thanks.
