I can write cow in 13 letters.

Can You?

You can win me and lose me but never buy me
You can not eat me and never want to part with me
I can make you cry or bring you joy
I am not a machine and definitely not a toy
You keep me but i am not forever just yours
You might find me in a case or on a shelf next to a vase

I am made of different materials and am at many events
If your lucky and fight hard I might be yours
