RYO filter tips add structure to your rolled smokeable, keeping the tip from collapsing or getting squished, restricting airflow, and preventing a smooth draw. In addition to structure, roll your own filters to create a much-needed space between your lips and the burning material, meaning you can smoke the entire content of your roll easier, without burning your lips and fingers. Finally, RYO filter tips ensure that you do not accidentally inhale the contents of your smoke.
