I have a Kooba Sienna in Moss. I purchased it last spring from an online boutique and used it faithfully for about 6 months. I put it in the dustbag and stored it for a few months. When I pulled it out last month, I noticed that the green color has faded to a yellow-y olive shade. I can't really describe it. I contacted Kooba about this, but they told me to contact the retailer and for them to contact Kooba corporate. I tried contacting the online retailer and I haven't had any response yet. Has anyone else had issues with Kooba leather bags fading? Honestly... for a $500 handbag, I would expect better quality.
