Love the look
Color: Mk Signature/Brown/Acorn, Color: Mk Signature/Brown/Acorn
This product was ordered, shipped, and arrived in a fairly quick matter. The packaging was extra carful, had been wrapped, styrofoam, etc. There is no duster bag which is kind of a bummer. It is a pretty bag which will be used as a purse, not so much for travel considering it’s extra small. It even has a luggage tag, which is so cute. The quality feels authentic and comes with actual MK tags. Very happy with this item, has plenty of space for a purse and a long strap to use as a cross body. Not my usual style so I wouldn’t personally pay the price being asked, but it is reasonable considering.

You're Gonna Love This Purse!!
Size: One Size, Color: Black
A beautifully made purse that is a perfect size for night or day. Metal features are lovely and I really like the option of a hand held bag or a shoulder bag. It is not what I would call a LARGE bag despite the product description.
