These small sun catchers distribute light very beautifully and due to their size, the shine is very minimal and will not blind the eye. However, although the shine is small it will still light up your room beautifully with thousands of little rainbows. 
Each sun catcher is attached with an additional chain that is used to adjust the height of the sun catchers or to wrap it around the mirror of a car, if desired. (Similar to wearing a necklace).
Sun catchers are known to take the positive energy of the sun and spread that positivity to the area. 
If you are placing this in your car please make sure that it will not disturb your driving. If you have history of epilepsy/seizures please refrain from placing close to the eye.
