These lightsabers cost around 500 dollars and are custom built using Class II lasers that are placed inside polycarbonate rods. Sound effects are also used to make the familiar noises when swiping and clashing 2 of them together. In the handle is a place for a AAA powered laser which shines through a semi-translucent rod. The polycarbonate rod is supposed to be very durable also. The hilt is made of steel. This makes them look authentic, but yet you can still battle it out with each other and not be afraid of smashing the lightsaber to pieces. 500 dollars will get you a fairly advanced and well designed version and you can pay up to 700 dollars for a Count Dooku style version.
