Here is a French package of "Wackers!", they have been found in Canada. 
But they are really just pogs or milk caps. To avoid copyright of the original/s, this company calls their circle cardboards Wackers & their metal/plastic heavy piece a "Smacker". Notice how neither of those words translate into French, but everything else here does. The pog set itself you've seen before, it's easy to recognize by the circle shapes with the logo on the back & how they are numbered. What's interesting is that they use Knuckles for the Smacker instead of Sonic when there's only 1 included. The French words there are basically what's included which is the plastic jar for them, and an instruction sheet on how to play it. (Folded inside jar) They're simply bubble carded...but look how totally 90s the card is with the colors going wild & scribbly design. This might also be from actual France too.
