Super hard toothbrushes. Made of high-quality nylon material. They are difficult to deform due to the strong structure of the fit of the bristles. They are located along the entire surface in the form of beams. This contributes to the least wear after prolonged use. After the service life comes to an end, they can be used on the farm. For example, for cleaning hard-to-reach small corners. The set comes with 8 pieces in different colors.
