Take a famous painting, add a cat, a magnet, and voila! You're speaking French. The magnets are 3.5" x 2" (the size of a business card). They're 30ml and glossy. Why do you need these magnets? Because it sends the message, "Look at me! I am so cultured!" and the message, "I don't take myself too seriously" and "Hey, I have a refrigerator."
