Tressence was really easy to work with. The package arrived very quickly in perfect condition - It's the real MacCoy- as in the real Mason Pearson Brush. I have used them for about 30 years. After a good twenty years of use, my Mason Pearson finally wore out. It is so nice to have a new Mason Pearson brush again! If you are wondering - hmm - are they worth it? Absolutely! They work better than any other brush and your hair looks and scalp feels great! Cost-benefit analysis - Mason Pearson is cheaper to use than replacing cheap brushes which damage hair and end up in landfills.
