Fuzzy ice, known in the British Isles as furry dice or fluffy dice, are an automotive decoration consisting of two over-sized, six-sided plush dice which hang from the rear-view mirror. The practice of Fuzzy Dice originated in the U.S. in the 1950s and is considered one of first items sold specifically to be hung from a rear-view mirror. While fuzzy dice were at the height of their popularity in the 1970s and the 1980s, they have since become increasingly rare.
