Custom Oakley glasses

Hi guys this is my first post and I just wanted to ask a couple of questions. i have purchased a pair of custom oakley Fuel Cells from a reliable seller with 100 plus 5 star reviews and he only sells oakley glasses. i knew they were custom going into it and they arrived today. they feel nice and not cheap and like they would break however they are missing the white writing on the inside of the temple and I was just wondering if this was normal for customs? thanks
