Simply thread through the end of any cleaning rod. Instructions for use: 1. Remove the head joint. 2. Slip pointed end of swab through the hole in the cleaning rod. 3. Cover the rod with the swab. 4. Push the rod through the flute and pull out the other end. 5. Push into the head joint and pull back out.
