Choose what to infuse: tea leaves, fruit, berries, herbs — whatever you want! Unscrew the top and add your tea, herbs, berries and more. screw the top back into place and click your infuser into your frank green. Steep and enjoy. Add your water and let steep for a few minutes. carefully remove your infuser by pulling up the metal handle (or leave it in!) put your lid back on to your reusable cup or bottle and enjoy.
