The Monroe Brush is the only Patented Houglass Shaped brush in the marketplace. Our Patent reduces blow drying time and minimizes the probability of carpal tunnel syndrome. Our brushes have been in the marketplace since 1999, and they are manufactured by Plastics Vandux in Colombia since then. We used to sell under a different name prior to branding under the Monroe name. Our brushes are recognized by their high quality and their unique performance. Always look for the patent in the handle to make sure you are purchasing the original.
