Comb Teeth too Fine

I was on a quest to get colorful combs for my clientele with darker hair.  I usually feel for the sharpness of teeth, the weight of the comb, and a few other tests.  However, this comb passed all my initial tests, but when I started using it, I found the finer teeth side was entirely too fine for even my finer hair clientele. The client's hair would not pass through the teeth. I am actually going to have to dispose of this comb unless someone can discover another use.  Any ideas?
