Graduation tassels are usually worn on a graduation cap during a high-school or university commencement ceremony. Each graduation tassel also can include a small metallic graduation year charm indicating the year, including options for past years.
A corn is usually very painful.  Corns can develop along the tops and sides of the joints of the toe especially along the edge of the fifth toe. They can develop in between toes when one of the bones of the toe rubs on the bone of the toe next to it and on the sole of the foot, usually near the ball of the foot. A corn feels like walking on a little stone.
You may have a corn or a callus if you notice: A thick, rough area of skin; A hardened, raised bump; Tenderness or pain under your skin; Flaky, dry or waxy skin; Corns and calluses are not the same thing. Corns are smaller than calluses and have a hard center surrounded by inflamed skin. Corns tend to develop on parts of your feet that don't bear weight, such as the tops and sides of your toes and even between your toes. They can also be found in weight-bearing areas. Corns can be painful when pressed.
