Nubuck is a quality top-grain leather, similar to suede. Heavy and durable leather, it has been gently sanded to create a soft, velvet-like surface. This exquisite flogger is sure to give a lasting impact. The stiff, heavy falls are flat-tipped and create an impressive thud. The handle is made of traditional leather, black to compliment the purple-dyed falls of this excellent flogger.
