When I worked at Hasbro, we had boxes around the building where you could put a letter and it would only be read by the president of the company. I used it to send product suggestions. A while back I tried o do the same for Funko Pops.
Start here: https://www.funko.com/contact-us
Once there, select Figure or Product suggestion from the list. Follow the next link.
Select a product type, enter a character name, add some details, confirm you are not a robot and Send.
The last time I was there, I asked for Funko to revisit the Arrow-Flash universe of the CW. About 2 weeks later Funko announced the impending release of a Flash based 4 set including Barry, Wally, Jay and Vibe. I was super stoked. Kid Flash goes nicely with both the Flash cast and the John Constantine piece I picked up on Free Comic Book Day to make a Legends of Tomorrow group.
Now Funko, I know you are busy trying to figure out an assortment for CW’s Crisis on Infinite Earths event, and of course we need later additions to the Arrow and Flash rosters, but in the meantime, I have to ask, where are my Black Lightning inspired Pops?
Its time for:
Black Lightning
Thunder
Lightning
and
Pain Killer
