Flat Fan / Small Fan

‘Flat Fan’ is a card shaped mini-fan. It uses solar heat as a source of energy which causes zero pollution. Also, it is thin and light like card so it is convenient to carry. To use ‘Flat Fan’, the user may snap the frontal wing to the proper angle so that the solar heat collector may absorb the sunlight. Then the motor runs by the solar energy and wings begin to flip to create cool wind.
