  • the conventional golf tee is made in one integral body structure using a wooden material or a plastic material.
  • a stick portion of a golf tee receives a strong impact by means of a head of a golf club at the moment when a player swings and impacts a golf ball, so the golf tee might be easily broken, which leads to a lot of consumptions.
  • an inserted golf tee might be pulled out of a ground by means of a strong impact at the moment when a player impacts a golf ball and might fly a long distance, so it might be lost.
  • the golf tee sometimes influences a flying direction of a golf ball.
