4mm terp pearls are the smallest size we make, built for tight buckets and small dabs where a larger pearl would crowd the airflow. At 4mm they start spinning with very little draw, so they get to work fast and keep your concentrate moving across the hot quartz instead of pooling in one spot. Sold individually at $2.99 in seven colors.

When to run 4mm

Pick 4mm if you are running a 20mm or smaller quartz banger, if you take small dabs, or if you like three or four pearls working at once instead of one or two larger ones. More pearls at a smaller diameter means more edges breaking up the oil, which is why a lot of low-temp dabbers prefer this size. If your banger is 25mm, step up to 6mm instead.

Seven colors, two materials

• Clear: borosilicate glass. The classic. You can watch the oil work and see exactly when the bucket is clean.
• Blue, Green, Red, Yellow: colored borosilicate glass. Easy to spot in the bucket and easy to tell your set apart from a friend's.
• Glow in the Dark: charges under light and glows between sessions, which also makes it the hardest one to lose.
• Ceramic White: our ceramic terp pearl. Ceramic holds heat longer and more evenly than glass, so it stays in the useful temperature range further into a dab. Opaque rather than see-through.

How to use them

Heat your banger, let it cool into low-temp range, drop your dab, add one or two pearls, then cap. Terp pearls only move when air is moving over them, so a carb cap is not optional. A directional or spinner cap pushes them in a circle and keeps the oil chasing the heat. Let the pearls do the work rather than chasing the oil with your dab tool.

Care

Soak in isopropyl alcohol, rinse with warm water, and let them dry fully before the next session. A short torch after a dab burns off most residue. Avoid dropping a cold pearl into a screaming hot banger, since thermal shock is what cracks glass.

FAQ

How many 4mm terp pearls should I use? Two to four, depending on bucket size. Start with two and add one if the oil is still sitting still.

Are terp pearls and terp balls the same thing? Yes. Same product, two names. You will also see them called dab pearls or dab marbles.

Glass or ceramic? Glass lets you see what is happening in the bucket. Ceramic holds heat longer. Both work, and plenty of people run one of each.

Do these fit a terp slurper? A terp slurper needs a matched marble set rather than loose pearls. Check our terp slurper marble sets for that.

Is this one pearl or a pack? Each order is a single pearl. Add the quantity you need to your cart.
