I'm not really that hard on bags, but I do tend to use them and forget about it. My most expensive bag is a kate spade, and I just carry it. I keep it in its cloth bag when I'm not using it. But I didn't protect it with leather spray, and it's only been conditioned once (by the SA at Nordstrom). I've even carried it on rainy days. It's 2 years old and looks perfect. I love the totally turnlock styles but after reading about color transfer issues and products causing bags to turn lighter, I'm scared to buy an MBMJ. Will I really need to treat it with kid-gloves? Please talk me into it b/c I really like his bags, lol!
