The Wahl Colour Trim Stubble and Beard Trimmer features innovative colour-coded guide combs, making it easy to select and remember your preferred trimming length. Simply match the colour comb to the desired length, indicated by a code on the trimmer. This trimmer helps maintain perfectly groomed stubble and a well-trimmed beard with its 8 colour-coded combs, offering flexible styling options. The Smooth Cut Combs are 35% stronger than standard combs and have rounded tips designed to glide smoothly through hair for a snag-free trim. Enjoy 60 minutes of cordless run time on a single charge, providing ample power for your grooming needs. The trimmer also allows for corded use if the battery runs low. For optimal performance and longevity, regular maintenance is recommended: oil the blades after cleaning with hygienic spray, and oil the trimmer blades after each use or daily for frequent users. Avoid submerging the trimmer in water as it is not waterproof. Precision ground blades ensure a superior cutting performance for effortless styling.
