Tomy is making more Gacha stuff, this time in Australia. Will these appear elsewhere? Yes! England has been confirmed at Funky Monkeys Skating Rink. Each gacha item contains 5 character magnets, each with a different design. You can collect Silver (shown here), Metal Sonic, Shadow, Knuckles, Tails, Sonic, Eggman & even Super Sonic! While Silver has only the same pose for all of his items, the other characters are shown to have more than one pose. (see Shadow art differing on the flyer) These are only 2 dollars each, so its pretty reasonably priced too. Additional info by CrystalKitsune
More magnet details! At right you can see the full set of Tails magnets, because he is so popular he gets a different art for each shape. Below is the ever-popular Metal Sonic set, however, though he is a fan-favorite, he clearly only has one pose. The file-cabinet drawer front has been decorated with ALL the magnets, so by looking at that photo you can easily see what the complete set looks like. In the photo below you can see the paper that came with them.
If you get them out of a gacha ball, they won't be in the bag seen above. Each character gets a star, a swirl, a star-ring, a circle & a diecut shape.
