These Ruby Terp Pearls are made from lab-grown ruby and provide excellent heat retention inside quartz bangers and compatible e-rig chambers. Available in tiny 3mm and 4mm sizes, they have plenty of room to move inside smaller chambers while helping spread concentrates across the heated surface. Ruby is a popular alternative to standard quartz terp pearls when longer-lasting heat retention is preferred.
