I have a vintage key charm that I treasure. It is comprised of numerous symbols of potency for luck and protection.
I had it cast in silver, and I finish each by hand.
I also made a version in bronze that you can buy here: https://www.witchsy.com/clothing/jewelry/key-talisman-necklace/
The key has the allure of the mysterious, wear your for fashion or protection.
Each measures 2.25" (5.7 cm) tall and 1" (2.54 cm) wide
Hangs from a 24" (60.96 cm) silver plated chain
Comes in a jewelry box, perfect for gifting
