Rebounded

I'm so flexible but I can snap.
So never push me too far.
I'm very strong but I can still break..
My strength depends on how kind you are.

I work well with my own kind..
Together we bounce off the wall.
But just like Humpty Dumpty..
I can't be repaired after bad fall.

I am resistant to extrusion..
I can bend to accomodate most needs.
If respected I'll stretch the extra length..
And I multitask when asked with a "Please?"

I can hold many items together..
And tidy up a messy space.
My resilience will always rebound..
My versatility can suit any place.

I will always make you look good..
And give your hair a modern style.
I can help you break bad habits..
If you wear me on your wrist for a while.

You'd be surprised how many times I'm needed..
I come in many colours, styles and brands.
My abilities are absolutley endless..
Im your hard working, loyal RUBBERBAND!
