These Feng Shui envelopes are filled with 3 coins - and symbolize good wishes and luck for the year ahead. The importance of the envelope isn't the cash held inside; it's actually the envelope itself. The red color symbolizes good luck and prosperity in Chinese (and other East Asian) cultures.
These tend to be placed under a front door mat to attract wealth, abundance, financial security and prosperity into the home.
Each envelope contains 3 chinese coins wrapped by red ribbon.
