Hi BBG! This is the LV Damier Azur Milla. It's a small pouch with one interior pocket. It has the alacantra lining so it feels very luxurious. Unfortunately it has been discontinued. I had hoped to also purchase it in monogram but I was too slow.Off topic - but which LV bag is this?
Here's a picture I took last year of some of my DA pieces so you get an idea of the sizing. The mini Pochette, followed by the Milla clutch, then the Pochette accessoire. The two Pochettes have greater depth. The Milla I use as a wallet in the summer, or sometimes as an evening clutch and it can accommodate my iPhone 5, a couple cards and a bit of cash. It is super slim. It will not hold a big key ring. I need a driver when I use it! (The LV gold key ring chain on top of the Pochette I bought separately and I use that instead of the vachetta strap to make it more dressy).
