Sky lanterns can be traced back more than 2000 years to ancient China. Sky lanterns can be used to celebrate all special events such as birthdays, new year, summer parties, weddings. They are the perfect quiet, stylish alternative to fireworks. These sky lanterns are made from fire retardant paper which is fully bio degradable. Simply remove the lantern from the packaging, unfold it and attach the small wax fuel cell. Hold the sky lantern open, light the wax cell and release the lantern once it is ready to rise. In calm windless conditions the sky lanterns can rise above 1000m and stay aloft for up to 20 minutes.
