The handle is rubber-like material along the tip of the brush, good for damaging the paintings. Little is bending the shaft of the brush to get behind the wheel sticks, that's good too. As against the useful length of the hair is not 37 cm but about 24 cm, but it must remain sufficient for most rims. Lifetime warranty on line registration. Edition after use: the tip of the brush has a rubber to protect the paint rims, but after the first use I lost this Appendix and suddenly the metal rods are apparent and very aggressive for painting. The two twisted metal rods that hold the bristles are too soft in the neck and the brush bends quickly, it is difficult to insist on an area because the axis of the brush twists as soon as we pulled more. We need another brush for this purpose.
