This St. Teresa of Avila holy card has the following prayer:

Let nothing disturb you; Nothing frighten you.
All Things are passing.
God never changes.
Patience obtains all things.
Nothing is wanting to him who possesses God.
God alone suffices.

The pewter pendant is 3/4in. x 1/2in. and comes on a 20 in. rhodium chain.

St. Teresa is the patron against sickness, headaches, and of people in need of grace.
