Can it be that here "REAL PREMIUM" is used as a name or the model / brand name (hence in capital letters) and are employed directly after the word "leather" to "genuine leather" to achieve the phrase? Maybe I'm wrong yes me, but after genuine leather looks the part for me neither from nor smells of it. Also stands in the article description anywhere of "genuine leather".
However, the processing is the material used, no matter what it really is now, quite handsome and durable and good, so that the pencil case was not a bad purchase total. It is precisely tailored, chic, does the job and looks after months still like new.
Due to the material question a star deduction, but recommended.
