About the product If I go one week without trimming my neck hair, I look like some sort of man-beast that doesn't quite belong in society. This is why it's essential to trim your neck hair on a weekly basis or at the bare minimum a bi-weekly basis. Now usually, your significant other or roommate bares the brunt of having to trim your neck hair. But you can trim your neck hair all by yourself without the need for a setup of 7 angled mirrors to see the back of your neck. The Barber's Edge is a device that gets placed on the back of your neck, and gives you the perfect line to blindly shave your neck while protecting the actual neck line so you don't accidentally trim anything that shouldn't be trimmed. You can attach the Barber's Edge hairline trimmer to the back of a hat using two included clips, you can attach it to a band that wraps around your head, or you could even just hold it in place while you trim your neck. Whether you like rounded corners or squared off corners on your neckline, the Barber's Edge has you covered. By default the device has rounded edges, but it comes with cutting lines that allow you to remove the rounded edges and use squared off corners instead. Perfect for use with the DIY back shaver, the Barber's Edge no look hairline trimmer comes with two clips that allow you to adjust perfectly to your neck hairline, and allows you to trim your own neckline in under 30 seconds Size:22x10cm material: plastic Package Content: 1PC Hair Template
