I'm new to Botkier. I love the look of the Biana (several women at work have it) & I was considering making the small one one of my next purchases. However, I was wondering how careful I need to be? If I get one off of eBay, do I have to watch out for fakes for this brand too? Since I'm not familiar with the brand, I was just wondering. Also, I did do a search for threads about them & the general consensus seems to be that the whole zipper/flap is a huge hassle, even though the bag is gorgeous? Thanks!
