How old are they?
Hiya Jeff!
I believe they came out sometime in the 90s, but I never knew they existed. LOL
I forgot to post this, but my Funko Pops collection of Super Friends figures is (for now) complete.

I say "for now" because there are a few characters that have not been created. If they do create them, I would get them.

If you click the pic, it gets bigger.

Green Lantern, Flash, Firestorm, Robin, Batman, Hawkwoman, Superman, Hawkman, Aquaman, Wonder Woman, Cyborg, Wonder Twins (Zan & Jayna) and their pet Gleek.
