With this dish brush, you can easily maneuver to wash the inside of your jars or other reusable drink containers. Brushes bristles are made of Tampico (from the Agave plant) and the handle is made of beechwood and metal. Each brush head lasts about 2-3 months with daily use and good care. Tip: Do not leave any wooden parts soaking in water as the the wood will absorb water and swell, causing cracks. Hang or place upright to dry after using. How to dispose: Once worn out, the brush head can be composted. The handle can be reused again with a new Replaceable Head!
