no. it can not found in anyboxes,
Only 3 ways to get kit card, Festival(+ Premium), watch AD 130 times in 15 days, or we can buy 1 Kit Card for 1000 tokens.
Well... by sell 1 kit card for 1000 tokens, GL try to make player to think, better buy Premium than buy 1 kit card.
at Festival, you can get free kit card but only the festival car kit card, Then with Premium you can get the past festival card.
worth or not worth? this depend on player. someone can think this worth but someone don't.
