Are my razor blades fake or real?

[Oakleykid]

Just bought these razor blades from a guy on ebay for $33. Need help identifying whether they are fake or real. All I can say is they don’t say razorblades on the inside of the earpieces. They are the vintage ones not the 30 year anniversary. The lens look great when I look through them, so they seem like oakley quality. They came in a generic cloth sunglass case, not oakley brand. I can take more pics if needed. Thanks in advance.

Not Razor Blades but rather Blades.

Razor Blades are not as tall.

They look OK to me.
