These 4mm Sapphire Terp Pearls are made from lab-grown sapphire, offering excellent heat retention for both traditional quartz bangers and compatible e-rigs. The compact 4mm diameter gives the pearls plenty of room to move and spin inside smaller chambers, helping spread concentrates across the heated surface for more even vaporization.
