DANGER TOXIC GASES! Let's face it, sometimes it's best to ' Give it 10 minutes'. When the air is particularly pungent, it's only fair to issue a warning (or gas masks) to those who follow for a visit. The caution cone will be seen at a safe distance giving notice of noxious air pollution & saving innocent bystanders from a nasal assault, whilst allowing time for the air quality to be restored by natural circulating currents. A great gift for the malodorous!
