Made with untreated beechwood and Tampico fibre (plant based) or horsehair. 5 cm. Replacement heads also available in a separate listing. Dishwashing brushes for any use: These soft brushes enable you to clean plates and cups thoroughly. The stiffer plant fibre brushes are ideal for non-coated pots and pans. Horsehair brushes are softer than Tampico fibre and more suited to dishes that require gentler brushing, like some coated or non-stick pans.
