Plastic washing up brushes pose the same issues as plastic toothbrushes - they are going to be in landfill for a hundreds, if not thousands, of years.
We use so many without considering the impact the plastic is having on the environment. And due to the type of plastic, they are not recyclable (however even if they were plastic recycling has a limit).
Our Blue Eco dish brushes are 100% plastic free. Bamboo wooden handle with sisal bristles and metal fittings. Approx overall length 23cm, handle length 18cm, head diametre 4.5cm.
Please allow brush to dry out completely in between uses, we recommend hanging with the bristles down and store out of direct sunlight. When the bristles get old, simply remove the head and replace. Replacement heads, available here.
