It's Andes mints!
To make this shimmery wreath, unwrap about six dozen chocolate-mint candies and glue the wrappers all over a 12 inch round-edged extruded (heavyweight) foam wreath. Then make "branches" with wrapped candies. On a large piece of cardboard, arrange the candies into six large and six small branches ( you'll need eight candies for each large branch and five for each small one, as shown). Trace around the candies, cuto out the cardboard branches, glue the candies onto each branch then hot-glue the finished branches to the wreath.
