The ROMA paint brushes are produced by one block system. This system is a result of a fusion between the bristles, the ferrules and the handle, making use of a special adhesive resin. This process ensure a better resistance for the product and do not allow the same to leave the bristles , even after a prolonged and continuous use of the paint brushes.

The ROMA wool rollers, both the natural wool rollers, the mixed and synthetic ones, are produced by the thermo-fusion system. This process do not use the adhesive between the leather / fabric and the polypropylene tube. To assemble it, the tube is heated to a temperature that the leather / fabric is molten straight in the plastic, offering the durability for the product and its resistance to the solvents.
