When the FlexIt® brush system was designed by groomers, they understood their three primary brushing tasks (Mat breaking, Undercoating, & Finishing) and designed a brush face specifically for each job. The brush heads have two different flexibility options: soft and firm. It is the flex of the head that drives the faces through the coat so effectively. This “flex of the head” also offers relief to groomer’s wrists and forearms, reducing strain and minimizing the likelihood of painful Repetitive Motion Syndrome. There is less snagging, less “ripping” and will reduce brushing time by up to 50%! The durable pads hold more pins than any grooming brush made, and can be pealed back to clean behind them, or to remove, straighten, and replace a bent pin. Add the option that FlexIt® is the only brush that puts two of these different working faces on a single brush handle, called the "Combo" Series (brushes with the same face on both sides are called "Twins"), and you will understand why they are considered the very top of the category. Each pin is electrochemically blunted and there is a 30-day, unconditional money back guarantee on every brush sold. To date, not one has been returned.
