Magnet "AKU"

myminifactory

The magnet bears a Japanese character signifying malice. Sano Tsukasa Sagara, the main antagonist of the anime Samurai X, adorns it on his back. The villainous figure from the animated series Samurai Jack is also known as Aku. Conveniently, an opening at the rear accommodates a standard ferrite magnet with a 2 cm diameter. These magnets are widely available for purchase.
