I know this is silly but it’s a rather slow day in East Asia (forgive me): I just accidentally stumbled upon this “special” mouse and mouse pad set [JP], which is unfortunately Japan-only (as was the golfing mouse pad and the one for gropers).
What can I say, the mouse buttons are shaped like boobs and the hand rest on the mouse pad is cleverly formed like a pair of breasts.
No, this is not normal in Japan. Price: $38.
