I bought a comb similiar to these, but not even close to that price. They have the wood teeth on one side and then the smaller on the other.
Metal of course and we use a conditioning spray prior to any brushing or combing.
I also bought a 100% all natural boar bristle brush (as that was what was recommending to me from someone on here at one time)...I bought mine for $20 at a local beauty supply store.
I really love them both!
