This is a RAKUWA neck from Phiten, featuring their highest-level Metax technology. It has a simple color scheme for a unified look. The V-shaped top creates a natural line in front of the collarbone, making the neck and face appear sharper. It fits naturally with business attire, casual wear, and formal wear. I have used it for about 3 months. There is some wear and tear from use, so please refrain from purchasing if you are sensitive to this.
