My blue bag is my mystery bag & one of my favs! I purchased it for my 18th birthday at a Marshalls for $150. I've researched it and I've seen the same bag (but in gold) on ebay going for $350. I've also seen similar bags in different sizes, but never my exact bag so as far as I know I'm the only one in Miami with one
I love the satchel because it's a casual bag, but it's still glam. I would say the fabric is good, it's sturdier then it looks, my only complaint is that the material can concave a bit from wear so you need to watch it to make sure it keeps it shape (a problem I've never had with any other coach bags).
