Dota2 the International 11 TI11 Grand Final tickets (only 2 tickets left)

I got five tickets of Dota2 the International 11 Grand final on 29-30 October. Two of my friends can't join so I am selling two tickets for $1800 or $900 each. I will grab the tickets at Singapore Indoor Stadium on 28 October so you can pick up on-site afterward. We can meet up in-person first in Sydney.
