★The brush is made of high-quality pine wood without scars and damage as the basic wood, with selected animal bristles as raw materials, and is made on a professional production line.
★The brush-based wood square strips are straight and square, with both rigidity and softness. They are taken from the same batch of raw materials to ensure similar density and weight to ensure the same wear and tear during use. The life span of the same set is uniform, making it easy to use and replace the entire set.
★The bristles are uniform in length and size. The traditional process of folding the bristles in half (double-stretching) is adopted to ensure the density and length requirements of the bristles. The bristles are twisted and tightened with high-strength cotton thread to ensure no shedding and no threads during use.
★Finished products are precisely cut to size, weighed and marked after natural drying, and grouped into groups according to the required number of pieces according to the machine size to minimize the weight difference of each piece, which facilitates group assembly, eliminates bias, does not vibrate during use, and increases stability. Extended service life.
