I don't have an Edith, but I do have a Chloe Patsy tote in Blanc. Since it's a very soft lambskin, I decided to go ahead and use Apple Care Conditioner and the Rain and Stain repellant on my Patsy, as well as all my Chloes and other bags. All my bags have turned out softer and without color change. I live in PA where the indoor air can be dry in winter so I don't want the leather to crack from lack of humidity. Since I have kids, pets and accidents do happen, I'd rather be safe than sorry!
