The "Smile Wristbands" for volunteers of the Paralympic Games were officially unveiled on Thursday.

Bearing the five colors of the Olympic Rings, the wristbands are a set of tokens modeled on the "Smile Beijing" theme. The wristbands are meant to promote harmony and enhance civic-mindedness among the public. The Paralympic version of the"Smile Wristbands" are specially printed with Paralympic Games and volunteer slogans in braille.

It's estimated that over 40 thousand volunteers from 27 countries and regions will serve at the Paralympic Games -- 90 percent of whom have already served at the Beijing Olympic Games.
