Choose a side when you purchase the ruff GEAR Leather Slapper with Holes 16.5 Inch.  One side of this slapper has five punched holes in the leather for a good pattern to emerge.  The other has a flat surface for fuller contact, or of course mix it up and count the dots afterwards!  The high quality leather handle is reinforced on the inside for less flex whilst in motion and is stitched together with tough thread, keeping everything at full strength.
