You can easily keep up a short beard with these beard trimmers for stubble beards. So you'll always have a neat, cared-for beard or short 5 o'clock shadow stubble. You have a stubble if your hairs aren't longer than 3mm. You can easily trim your beard with an adjustable comb attachment, or with various separate comb attachments with different shaving lengths. The smaller the difference between these lengths, the better you can fade your beard.
