The MK store is one of the worst places you can go for authentications. Half of them haven't worked there very long and know nothing about the older bags and very little about the newer ones. They are even told not to authenticate anything by the company. Often they will tell you a bag is fake, just so you will buy one from their store! Very biast opinions from sales clerks who have very little knowledge of a product that has been around since 1981.Thanks everyone.
I got them from a source I know has authentic goods, but sold them to a buyer who was insisting they were fake and claimed that she had taken them to the MK store and been told so. She seems to realize now.
Glad it all worked out for you. Merry Christmas!
