For the 2nd year in a row, Funko will be at E3. There will be a nice handful of exclusives that will be available:
Glow in the Dark Ciri (Witcher III)
Shimmering Blue Kait Diaz (Gears of War)
Excavator Armor (Fallout 76)
Lion Form Sora (Kingdom Hearts III)
Hanzo & Genji 2-Pack (Overwatch)
Donald Duck POP! PEZ (Kingdom Hearts III)
They will be exibiting along side GameStop at E3, and it is likely that most of these will be shared with GameStop.
