The replaceable head for the classic stainless steel dish brush is made of untreated beech wood and natural fiber fiber. With the dishwashing brush, you can replace conventional dishwashing sponges made of foamed plastic, which must be replaced after a short service life. With the replaceable head, you don't have to replace the entire brush every time, just replace the worn head. The replaceable head is made of untreated beech wood and natural fiber fiber, so that it is completely biodegradable and you can dispose of it in the compost.
