I just think this is a great idea, interchangeable covers. One bag, many looks.
Basically the coolest. bag. EVER!! Here's how it works: you pick a bag (big or small). That is the basis for your new purse. Then you customize it with shells. The shells come in a wide variety of prints/styles (some even have extra pockets on the outside). There is currently more variety for the smaller bag, simply because that's the bag the company started out with. However, they keep adding new shell styles each month! Anyway. Once you get your shell, you just snap it onto the bag. It's a very firm magnetized grip and you have to tug on it for it to come off, so there's not really a worry of it coming off in public. When you're tired of that look, you just switch the shells....thus, preventing you from switching out the entire contents of your bag, each time you want a new look. PURE. GENIUS!!
Love the bags! I have the smallest and the medium size and love to change out the covers. So versitle & fun! I will never buy another bag.
