Methods of assembly:
1. Battery box connects diode. (Note: the positive and negative pole of the line, the positive pole for light bulb long foot, the negative pole for short foot; the switch side must not connect, prevent the short circuit.)
2. Install the base and put the diode on the stick.
3. Insert partial catheter from top to bottom.
4. Insert optical fiber lamp.

Principle:
1. Fiber-optic lamps are energy-saving and artistic modeling new lamps. It combines a bunch of high-brightness side-luminous plastic fibers with a high-brightness light source at one or both ends.
2. The optical fiber is polymerized by liquid polymer compounds. It has the characteristics of strong light conductivity, electricity saving, durability, no heat, no pollution, bending, wide range of environmental adaptation, safe use and so on.

Notes:
1. This product does not contain paints and pen brushes. Batteries need to purchase by yourself.
2. Please allow 1-3cm measuring deviation due to manual measurement.
