Vintage Glowing Rosary Necklace

2.5 foot (5 feet if taken apart) long, large glow-in-the-dark rosary necklace. 

The medal/pendant is two sided, with the head of Christ wearing a crown of thorns in front, and what I believe is Our Lady of Mount Carmel on the reverse.

This is from Italy. It will glow, and fluoresce in black light environments.

The crucifix is over 2 inches long.
