Optical fiber 0.5 mm, coil of 10 m Art. FB05

Coil 10 meters of optical fiber with a diameter of 0.5 mm.

This synthetic fibers, which are lit at one end, transmit the light at the other end.
In the implementation of the starry sky is recommended to use fibers of different diameters, in order to portray the scene as realistic as possible: they look at the night sky we see not all stars are the same, but differ in magnitude and intensity.
