ADJUSTABLE LENGTH: Don't worry about the wrong size! Our hair trimmer template has an adjustable circular design, suitable for both adults and children. It's a great option for those who want to achieve DIY haircuts at home. WORKS PERFECTLY: Our neck shaving stencil is made of skin-friendly silicone and elastic material, specifically designed to comfortably fit the contour of the back of your neck. Trim your hair along the neck hair guide without the help of another person, keeping your haircut neat by removing excess hair.
