"I have been selling the same Diamond instruments since 1981. They are a premium brand  that is sold all over the world for $6 or more. I private label and package in zip lock bags without the fancy boxes or gold plating or colorful striping or expensive marketing. You only pay for raw cutting power and you get alot of cutting power with my diamonds. If the diamond does the work you don't have to. Neither does your handpiece. Try my diamond...you will never go back."    

(One little thing I should mention: I am not permitted to disclose the actual brand of this instrument...so please don't ask me)
