Caps Game Pogs or Tazos are from Australia. This is the full set

Here's the full set of 30 Caps Game Sonic Pogs, complete with its 2 Slammers! Caps Game made these for Australia in 1995. There are 30 pogs, 20 of which glow in the dark! The first 10 pogs (left photo) don't glow & have black backs. The rest do, & have purple backs (seen above) each one is also numbered.
As is the usual with pogs or caps, you get some typical art, & then some non-typical or uncommon stuff too. The first pogs are mostly GameGear related. You can see how they pulled images like Spring Riding Sonic, Knack, wierd Knuckles & Rocket-shoe Sonic from the GG covers. The rest, as you can see have geometric or abstract backgrounds...each with white. It's the white bit that's likely to have the "glow paint / ink" on it. Climbing & walking-punch Knuckles are seldom seen, as is the random rollerblade / jet ski Sally (she was on USA pogs as well) This is an interesting set! You may even be able to buy some of them at http://spakatak.com Info by SpakAtak

The yellow tube case to right is the perfect place, as it has Sonic's face in the texture on the top. Tube cases for pogs were very popular. This one is meant to hold the whole set. They were sold 10 at a time, but there were 30 in all.

All the names are really obvious like "Sally Jet Ski" & "Standing Knuckles". The next sheet shows how to play it which, as you'll notice features modified stock art including 'getting ready to run' Sonic changed into "slammer throwing" Sonic. Basically you spread caps/pogs around on the ground, then throw the heavy slammer at them trying to flip them to keep the ones you flip. The first sheet is from the "Slammer & Tube" pack.
