Silicone, which sounds odd for an ashtray until you have used one outdoors. It will not chip, will not shatter, and will not scratch a table when the wind moves it.
Easy to clean, flexible enough to pack for a trip, and available in brown, black and other finishes. Made for the patio, the boat and the campsite.
Silicone construction · Easy clean · Heat resistant · Flexible and packable · Multiple finishes
The travel and outdoor ashtray. Throw it in a bag and stop worrying about it.
