This is actually a fun little thing I've been doing on the side. They're hard resin pins.
Since I'm still experimenting and getting used to it they're currently only 5 each, that'll go up once I get more familiar and consistent. Until then, everything is more or less experimental. Each is more or less unique refer to the numbering chart for specifics!
All pins glow in the dark to a degree. See image for how they look. White/Light Colours seem to glow better and longer.
Standard pinbacks, see photo for more details.
Thanks for looking.
