The 2mm Linea tennis bracelet is delicate if it is mistreated.

The Linea 2mm bracelet will snap if you twist it with some force, if you pull it with some force it will not snap so it is important to know this when you put your bracelet on or take it off.
This is the mechanism of the tennis bracelet. The small parts are linked by very small and flat T-bars so if you twist the T-bar enough it will snap, however, it will not snap if you pull it.

Please watch this video to see the mechanism works:
