spakatak.com Tazos Guide
Tazos are also known as Flippos, POG, Caps, Slammers, Whammers, Whackers, Trovs, Kinis, Blasters, Milkcaps, Clippos, Trouncers, and probably many other things, depending where in the world you are located.
Here in Australia the most common name is Tazo or Tazos, and as such, whenever I refer to Tazos, I mean any of the above, unless specifically referring to a set (i.e. a set that says 'POG' on it, I will always refer to as POG, and so on).
We recently had an issue with a malicious attack and have lost some image data. I am working to restore what I can :/!
