The Crest of Dagon from The Shards of Illumination, the fourth Elder Dice campaign.
These pins resemble melted wax seals, but the material on these is glossy, enamel-coated metal with a metallic gold clasp on the back.
The glossy enamel on this thing catches light like real melted wax, which I didn't expect from a metal pin. I've had it on my jacket for two weeks and the metallic back hasn't loosened or scratched once.
The pin has a nice weight to it and the enamel coating makes the melted wax look convincing up close. I've got it on my dice bag and it hasn't scratched or dulled at all after a month of handling.
The glossy enamel really sells the melted wax look—my friends thought it was an actual wax seal until they held it. It's solid metal too, so no worry about it snapping off my bag. Very happy with this.
