This is my "Illuminati" Pendant. I've convert the ancient symbol into a physical pendant, suitable for hanging. In the photos you see a "White Strong & Flexible" version next to a Stainless Steel version. The plastic version is reasonably tough, but if you plan on using this for jewelry, or as a pull tab for a jacket or backpack, I would suggest getting the very strong Stainless Steel version. It should last you years of wear and tear.
To attach to a Necklace or Pull Tab, use a Split Ring, like those used to attach keys together.
