Fresh

Metallic notes smell like the crisp, ionised air after lightning strikes—think ozone mixed with the cool tingle of licking a battery (not that you should). Imagine the sharp, almost electric scent of fresh pennies, or standing near high-voltage electrical equipment. There's an ozonic, slightly mineral quality, like inhaling deeply at the moment rain begins, yet cleaner and more synthetic. It's not unpleasant; rather, it's futuristic and startlingly fresh, almost salty-sharp, with an ethereal, airy quality that feels almost metallic on your olfactory nerves.

Gourmand

Vanilla smells like warmth wrapped in sweetness—imagine the comforting aroma of freshly baked vanilla sponge cake, or a warm bowl of vanilla custard on a winter's evening. It's creamy and soft, almost edible, with subtle woody undertones and a hint of spice that recalls cloves or nutmeg. Pure vanilla is surprisingly complex: it's not aggressively sweet, but rather enveloping, like condensed caramel with a touch of earthy depth. It smells like indulgence and safety simultaneously.
