Neef Hog 1150 Brush series is the 100% interlocked hoghair blue handle range. The 1150 hog bristle leaves brush marks in the paint film where required and only the best quality Chungking bristles are selected. Neef Hog 1150 Brush bristles achieve greater spring by adding an extra length of hair inserted into the ferrule, forming a mould and oven heating for a short time. This quality control enables the 1150 Brush series interlocked bristle to retain its shape and resilience over many years. Chungking bristle hoghair is specially prepared to give the best quality results over many years. We highly recommend these brushes to oil painters. If you look after them they will last a very long time and even improve with use.
