5 in 1 Clipper Blade #9 to #40 Fine. The '5 in 1' Blade group is a specific blade group that fits on specialty clippers such as the Arco, Bravura, Chromado and Li+Pro interchangeably. They are easily detachable which makes them easier to clean than standard blades that require screws to be taken out for cleaning and maintenance. The '5 in 1' blade is unique because it has 5 of the top used blade sizes integrated into just one blade, saving time and costs. This is a standard blade. It is meant to be used on animals with fine hair and it easily adjusts to blade sizes #9, #19, #15, #30 and # 40. This is a standard blade because it is typically the blade that comes already attached to clipper units. (Except for the current Li+Pro). Fits Wahl ARCO SE, Bravura, Chromado & Li+Pro clippers. Cutting positions #9, #10, #15, #30, #40.
