The bag was a Louis Vuitton. I didnt have it authenticated. I thought it was real at first. Then I put it on EBay and another seller contacted me and told me it was fake. I thought I had an eye to spot it. The telltale sign should have been in the datecode. (Factory of production was "DP" which doesnt exist.)
I think to make sure you need to authenticate that bag. You could send pictures to Authenticate This.
How can you just trust another Seller that e-mailed you?
Are you sure the date code is DP instead of SP? On some bags, it is hard to read it.
