Terp Pearls 6mm — 10 Pack Review

Terp pearls are one of those accessories that look like a gimmick until you try them — and then you never dab without them again. The concept is dead simple: drop one or two small glass balls into your quartz banger before you heat it. When you cap the banger and inhale, the airflow spins the pearls inside the bucket, continuously spreading the hot oil across the quartz surface. The result is more even vaporisation, better flavour from lower-temperature dabs, and less oil pooling and burning onto the floor of your banger.

Size and Compatibility

These are 6mm borosilicate pearls, which is the sweet spot for most standard 14mm and 18mm bangers. For smaller bucket bangers (20mm or less), you might want 4mm pearls instead. For regular 22-25mm buckets, 6mm is perfect — two pearls spin freely without jamming. The borosilicate glass is the right material choice: it's inert, won't react with your concentrates, and can handle the thermal shock of going from room temperature into a hot banger. Rubies and sapphires conduct heat better, but at £5.99 for 10, borosilicate is the obvious starting point. Check our dab accessories page for matching carb caps and bangers.
