It all came from nature and we just added efforts to capture the beautiful smell and look longer(average life is 1 year. May differ depending on temperature, humidity and other elements). Appx 18-22 inch tall branches in a bunch. Smells fresh and soothing just like fresh eucalyptus. May use for the bathrooms for aroma, diffusers, flower arrangements, and more fun and creative home decor ideas. One unit is shown as in the first picture. 4-5 branches with full of leaves in a bunch/unit.
