A large loss is visible at one side of the base. The shaft of the penu is cylindrical in shape though flares out towards the base. The penu is topped with a transverse grip, upturned at each end. A small hole is visible near the centre of the grip. The penu is dark in colour. A faded red sticker is adhered to the pounding surface at bottom of the pounder.
