This CyrusCoffee piston brush is very easy to use.
The handle is made of lotus wood.
However, the brush head (where the hairs are attached) is made of plastic (nylon) to prevent the disadvantages of wood in this part of the brush. After all, a wooden brush head will start to show cracks over time because it gets wet and dry alternately (see one of the images). And then coffee residues and other dirt could get stuck in there. This brush with a plastic brush head does not have that disadvantage.
Please make sure you order the right size; 51/54mm or 58mm.
Please note! In some images, the brushes are nicely photographed together. However, the package contains 1 brush of 51/54 or 58mm depending on which one you order.
