Used in high level contact sports such as Boxing, MMA and Kickboxing, the Eye Iron is a crucial part of a corner's kit.

Known by many names such as Endswell, Enswell or No-Swell is a small piece of smooth metal with a handle.

Kept in an ice bucket and best used when cold, the Eye Iron can help reduce swelling from cuts and bruises. This is done by applying direct pressure to the affected area. The cold causes the capillaries beneath the skin to constrict, reducing blood flow to the area.
