Remove the protective covering on the badge holder to expose the sticky adhesive.
Attach the desired referee badge to the badge holder adhesive. Ensure that the adhesive bonds with the badge fully as soccer referees are often called to work in adverse weather conditions and a lost badge can be difficult to find on a soccer field.
Place the badge on the referee jersey and make sure that the Velcro bond is secure. All referee jerseys come with a standard Velcro disc over the left breast pocket where the badge should be attached.
