What you see below is a Flatulence Deodorizer. It’s a charcoal cloth pad that’s supposed to be taped inside your underwear to lock in odours associated with passing gas (AKA farting).
The description for the item is quite descriptive and precise:
When intestinal gas is expelled the flatulence filter pad absorbs the gas odor normally associated with the gassy discharge or flatus. Those with digestive disorders such as IBS, Irritable Bowel Syndrome, Lactose Intolerance, Diabetes, spastic colon, Crohn’s, Colitis, Celiac, menstrual odors, diverticulitis, will regain confidence, end embarrassment, live life again, and enjoy freedom with this inconspicuous pad. No more smelly episodes, horrible flatulance odors, with these pads that are placed in your undergarment or panties.
They also go on to say that wearing a flatulence deodorizer is like wearing “charcoal underwear.” Because that sounds comfortable.
If you can’t stand to fart in public, you may want to invest in a disposable 10-pack of Flatulence Deodorizers for the low price of $29.95 — or you could just let it rip for free.
