Science Gear TS-N1 Iron Set - 6 Clubs Iron set from a local club maker in Shinbashi. Please check the manufacturer's website for details such as loft angles. This model is easy to use for beginners to advanced players. Uses Sticky Metal, which is softer than soft iron and doesn't rust even without plating. Features a club-specific flow design, preventing slices on long irons and hooks on short irons. The club-specific hardness design controls the ball's friction coefficient at impact, achieving a ball that stops on the green with carry. There are scratches from normal use.
