These are Medallion sets, and Magnets for the WWF Bungeez game.
What is the Bungeez game?
I have no idea. It must be something 9 year olds were into in 1999.
Was it like Pogs? I don’t even know how you play Pogs so I’m totally lost on this.
“Bungeez” reminds me of when Beavis would call Butt-Head a Bunghole.
