The round bells have a thumb screw that is used to hook them to a rod tip , I put them on the rod just below the flag . When you get a flag the spring action of the flag rod rattles them well . After I break the thumb screw I put the stem in the oval hole in the flag , since the flag is hard plastic . I hate to give Wal-Mart the business but they have the bells there (at ours) . Good luck , Jake
