Thank you for the speedy reply, t!
I contacted the seller and asked for pictures of any engraving on the hardware, but all he provided were the pictures attached so I don't think the hardware has any engraving. He did mentioned that there is a SANYO label on the tag and gave me some background info.
Here is what he said, "As you may know, there used to be two kinds of BURBERRY in Japan.
One of them is authentic BURBERRY LONDON. The other is BURBERRY produced by SANYO Co.Ltd. in Japan.
SANYO had an exclusive license from BURBERRY in the UK, though the agreement has already been expired since last summer in 2015.
Actually, this shoulder bag was made by SANYO. Please take a look at 1st picture in which you can see a white tag inside the internal pocket. The company name "SANYO" was written on the tag. So, this is definitely authentic Burberry Blue Label made by SANYO.
Please understand that SANYO's BURBERRY products are authorized by BURBERRY Headquarters. They are NOT counterfeit. Of course, the products of Blue Label are also authorized as authentic BURBERRY products."
Please let me know what you think. Thank you so much terite!
