With innovative colour coded guide combs, the Wahl Colour Trim Stubble and Beard Trimmer makes it easy to remember your preferred trimming length. Simply match the colour comb to the length you need. This is indicated on the handy code on the front of the trimmer. Maintain perfectly groomed stubble and a well-trimmed beard with the 8 colour coded combs, providing flexible styling capabilities. The Smooth Cut Combs are 35% Stronger than our standard combs. They also have rounded tips designed to glide through the hair for a snag-free trim. The Colour Trim has a 60 minute run time from a single charge ensuring you have enough power to complete your trim. The cordless option gives you freedom to move whilst styling. If the charge starts to run low, simply plug in to carry on trimming. Maintenance In order to ensure that you get the life and performance out of your clipper or trimmer, we recommend regular oiling. Blades should be oiled after cleaning with our Hygienic spray . Clippers should be oiled with our Blade oil after each use. Trimmers should be oiled once a day or after several usages. Make sure not to fully submerse trimmer in water, as it is not waterproof. Read our guide on Blade Maintenance .
