One of my LGS sells keyrings made from projectiles, or cartridges without primer, that sort of thing.
Real components, not plastic or obviously 'fake' ones.
Here in VIC empty brass in your pocket is legal, WA it's not?
If someone makes an innocent mistake and flew to the forsaken west (soz ) with something forgotten in your luggage what're the chances you'd actually get done for an ammunition related storage charge?
