Are aluminum seamless combs ok?

I've been having a hard time finding a seamless comb, and am fearful of combing my hair with anything else. I bought these combs today, as it is seamless...Just wondering if it will do or there is anything I should be aware of...ty

I paid $5.79 and $4.29 at BSS. I also bought this comb for $1 http://salon.wimexbeauty.com/Mercha...n=PROD&Product_Code=A10703&Category_Code=4008 and it is actually seamless. I'm starting to wonder if all there combs are.
