This 3 piece terp bead set includes a mixture of bead sizes that are perfect for use with the Terp Slurp Banger. Terp beads assist by stirring concentrates via airflow or regulating airflow as a marble cap. The approximate bead sizes: 25mm, 14.5mm, and 6mmx16mm and are sold as assorted colours that may differ from images. Please Note that the terp slurper bangers are sold separately and are shown for illustration purposes only. **Caution:** Only apply heat to the bottom dish of your terp slurper banger. Heating the bucket where the centre bead is located can cause thermal shock and crack it.
