The mistake appeared on the “Stuffed Pokémon Fit Coil” (“Coil” is the Japanese name for Magnemite), that was on sale from 15 July 2020 to 15 January 2021.
Fans of the franchise will know the magnet on the left of Magnemite’s body should not be red on top and blue on the bottom.
“It’s not defective to me–its imperfection is what makes it so special!”
“It might be an ‘error coil’ but that makes me love it even more.” “I can’t bring myself to part with it so I just bought another one!”
