While I was reading the book Ready Player One by Earnest Cline, I was inspired to make this series of copper keys.
The book is a story about a future world where virtual reality IS reality for most people, and a worldwide quest is perused to find a treasure whithin the game.
The copper key is needed to unlock the first gate in the quest.
Here is your own copper key, set with a quartz crystal. Wear it and let it open a gate you may be guarding in your own reality.
This comes installed on an adjustable sliding cord.
