Brushes are important tools that are multi-usable. Just think of covering with egg or brightener or greasing your baking tins and baking tins. Bread brushes are again very useful for brushing bread.
Baking and Cooking has brushes made from various materials, such as brushes with nylon hairs (these are Halal), but also brushes with synthetic hairs or animal hairs. The bread brushes are made of plastic and have polyester hair.
