Official Cases on Ali Express

Has any one of you guys bought official case OP3 case from Ali Express (www.aliexpress.com)?
I want to buy the original not some china made copy and only Aliexpress delivers to where I live.

If you have bought from aliexpress, Did your case had a Evutec logo inside the case? (original case has it and none of images of the cases at Aliexpress shows the inside of case)
If the case you bought from Aliexpress has Evutec logo, can you send me a link to that item on aliexpress.

thanks in advance.
