There are many sunglasses in Iron Man 2.
Instead of boring you with background on the movie which you dont care about, here they are:
1. Vonzipper – Fulton …. pair Tony wears when sitting in the big donut.
2. Sama – Deco 3 …. pair Ivan is seen wearing.
3. Initium – Inituma All-In …. pair Tony wears when he is in the Senate court and they are trying to get Tony to hand over the suit to the government.
