bait and switch car parts

So I bought some gaskets online that are the image on the left. I received the ones on the right.
I want to return them but the vendor says they're indeed the same gasket(lol) and the one on the right is superior and much thicker. Don't look thicker to me.
But earlier you said they were the same??
I have a poor experience with these perforated style gaskets, especially on headers.
Paid with Paypal, overseas vendor.
