Special Pen in a Mystery Box

Born in a jewellery factory,
Engraved with a name,
Shaped like a kiwi's beak,
Shining in the sunlight.

Seeing flashing dark and light,
As my owner opens and closes my friend,
My only friend,
The mystery case.

Made out of metal and gold,
With a black coloured pen inside,
Smooth like a dolphin
With weird reflections.

I am happy where I am,
Shining, shining, shining bright in the sunlight,
But I just wish
My owner would use me more often!
