It’s 10SGD a piece with no balance in them. Limited stock too…a little surprised it hasn’t run out yet because Singaporeans have been known for snapping up certain exclusive merch fast!
Also I checked with other friends and it seems that it should be available at a lot of Golden Village cinemas there so it shouldn’t be hard to get.
(The EZ-Link card is what Singaporeans use to pay for public transport around the island!)
