These were sold through gacha gacha machines (coin machines). According to the pamphlet, there are 12 erasers, but it seems that the erasers themselves came in various colors. Have confirmed through photos that there are at least 18 stickers.
Might also be called SD Sukeban Deka Stickers, but technically no “super” in the official name.
These look very similar to the cards in the other set, but these have writing on the front (usually that character's catchphrase). The art for this set comes from the Bandai video game.
