These T-shape pins are designed to create a neat and elegant updo such as a bun or French twist. They lay flat against the head, making them a comfortable accessory when sitting in the car or working in the office. These come in a beautiful dark brown tortoise color pin and a fun multi colored pin in red, green, white, and others -- perfect for the holidays. I love the T-shape because they show on the top of your bun or updo and add such an elegant touch!! They measure 4 inches long.
