Scientists believe that fish can smell one part per million, so if your hands have touched food, insect-repellent, gas or anything else, these and your own human scent transfer onto your bait. That's where the Fish-D-Funk Fish-Catching Formula Hand Wipes come in. By cleaning your hands with Fish-D-Funk's exclusive Double Down™ technology, you'll neutralize and counteract these fish-spooking odors at the molecular level. Formula will not harm live bait. Per 30 wipes. Made in USA.
