I was on an Amtrak to Chicago when Aunt Flow decided to pay me a surprise visit at the very end. When I got up from the seat to disembark from the train, a huge trail of blood slid down the side of my leg!! I was mortified. I tied a jacket around my waist, cleaned up the visible part of my leg with a hand wipe, and rushed to the women's bathroom. I changed, then rinsed my shorts in the sink, dotted the stain with this pen, rubbed it in, rinsed again. Did this a couple times, dried it using the hand dryer, threw it in my backpack, and forgot about it. When I pulled them out again... it was as if aunt flow had never visited!! This product is pricey but so worth it when your favorite pair of white-striped blue shorts gets stained. Highly recommend the investment!
