Discreet Antimicrobial Carbon Technology
Does :your friend" have problems with smelly gas? Look no further; your smelly "friend's" flatulence problems may be over. Meet Subtle Butt™ disposable gas neutralizers.
This pack of 5 saving graces (also affectionately known as gas pads, fart pads or fart filters) effectively filters the odor caused by flatulence; simply stick one in the right place and you're ready for a chili cook-off.
Each 3.25" square filter is made of soft fabric with an antimicrobial treatment on the side touching the skin. The fabric is impregnated with activated carbon, which faces the underwear or the pants and has a vast surface area for bad odors to adhere to and get neutralized. Two adhesive strips are strategically placed so you know which side is which. And at around 1/32" thick, you will never know it's there.
