BRAND NEW WITH RECEIPT PRADA BRIEFCASE

I bought this as a gift for my husband and he did not want it, I purchased it in the Prada boutique (NYC) and the return window passed and I could not return it. It is brand new, never worn.I purchased a separate detachable strap so it can be worn as a messenger bag (I have receipts of both items.) Comes with dust bag, authenticity cards, original receipts. It is still all in original packaging, bag, etc..Only serious inquiries please... They don't even make this one anymore, similar one with same leather is running @ $4600 @ prada Thank you
