Buddhist Prayer Wheel with Hidden Prayer Scroll Locket

Prayer wheels and scrolls have written prayers inside them. 

The locket comes with a metallic chain, unlike the black thread shown in the picture 

This locket contains a  central spindle. It is within a casing of a locket. Tibetan Buddhists believe rotating the prayer wheel while reciting a positive sentiment or wish known as a mantra releases the prayers and combats negativity.
