Well-designed from solid brass with an antique rustic finish, these will last for years to come, event after event. The two holes, added to the actual design, make it easy for them to be sewn firmly onto your leg wraps. Each is approximately (2.4 X 1.6) cm when measured. These come in a pair for better utility. Make sure to consider cleaning it once in a while with a brass cleaning agent such as Mirror or any similar product.
