A word of your wisdom, please ladies - do all Stella Falabellas, even the earliest ones, have YKK zippers? Mine looks entirely genuine but the zippers are marked with single D, H, or R letters, not YKK. Thanks so much....
 

Why dont you authenticate these horrible fakes BEFORE bidding ?
This is a fake. Sorry.
 
Can someone please help me, I bought this on eBay and it just arrived I can still open a case if it's not genuine, I worry about it and not sure who else can help me:sad: I will provide all selling details below :
