Everyone knows that smoking is a dirty habit. And it goes without saying that it's pretty terrible for your long-term health. But despite smoking's bad rap, ashtrays themselves remain pretty cool among lovers of design. Perhaps it's because they're tied to this verboten behavior—it gives these little receptacles an air of danger.

I'm not exactly sure what it is, but there's definitely something cool about them. Especially the swanky designer options or quirky vintage ones from that bygone era of casual smoking. An ashtray is now like a piece of art that adds a subtle shot of throwback cool to a coffee table, entryway or desk. Plus, they're practical—making for the perfect catchall for keys, AirPods and loose change. Or they can serve their original function and house a smoldering stick of palo santo or incense.

Fred Castleberry, founder and designer of F.E. Castleberry, has amassed an impressive collection of old hotel ashtrays—some of which are for sale at his shop. “The best souvenirs are not bought ... they're lifted,” he says. “Some I've nicked myself while others I've sniped on eBay.” These repurposed trinket trays remind us of the places we have been (or would like to go). Something we've been doing a lot of lately. So if you don't have one, let us make a few suggestions.
