Each cabochon comes with a discreet retractable ball that slips into the rail of you bracelet or cuff with a recognizable light click, the distinct sound of the engaged mechanism.
The cabochons are interchangeable, easy to manipulate and placed according to any of your desire.
It is important to insert the first cabochon with the ball to the left.
When all the cabochons are inserted into the rail, you will just have to screw the safety cap.
This cabochon will protect the mechanism from any involuntary movement or manipulation.
