There are many different kinds of leather pads on the market such as antelope, goat, cow or kangaroo leather. The finer the leather the smoother the surface is. Leather has many small pores that allow air to go through it making unprepared leather not suitable for good pads. The L&P leather pads are all double sealed from the inside as well as from the outside to guarantee a good seal as, and prevents them from sticking, which can produce a very irritating production noise. These pads can easily last for 5 -10 years. They will become harder over time and due for replacement as they become noisier in their old age. We offer our leather pads in white or black.
