HandBag For Girls

One of my friends purchase a hermes handbag,I seach on the website,it shows many high replica hermes handbags replica,I am wonder what’s different between original one and replica one?

I saw these Hermes Handbags selling on Ebay for $17,000 (they sold at this price). some where even listed at $64,000.
Who buys these bags and why? they’re nice, but with leather and silver finishing they don’t seem worth it.
