Highlights
- Lab-grown opal: Each pearl flashes color as it spins, and opal's density holds heat evenly for consistent vaporization.
- Five colors: Black, Blue, Green, Yellow and White opal to match your rig or cap.
- Two sizes: 4mm for quartz bangers and slurpers; 2mm for e-rig chambers like the Puffco Peak and Pivot.
- Sold in pairs: Two pearls per pack, the standard load for a spinner cap.
- Spreads concentrate: Spinning pearls keep oil moving across the hot surface so nothing pools or burns.
- Easy to clean: Soak in isopropyl alcohol; they are not affected by heat cycling.
In the Box
- 2x MJ Arsenal Opal Terp Pearls: One pair in the selected size and color (banger not included).
Description
MJ Arsenal Opal Terp Pearls are made from lab-grown opal, so they throw flashes of color as they spin while holding heat evenly across the bottom of a banger. Sold in pairs, they come in Black, Blue, Green, Yellow and White, in 4mm for quartz bangers and slurpers or 2mm for e-rig chambers.
Use them with a spinner cap on any MJ Arsenal banger — they are made for the brand's Full Weld Quartz Terp Slurper and blender — or drop the 2mm pairs into a Puffco Peak or Pivot chamber. They sit alongside the quartz and ruby versions in our terp pearls collection.
FAQs
- 2mm or 4mm? 4mm for quartz bangers, slurpers and blenders. 2mm only for e-rigs (Peak, Pivot, Proxy chambers); they are too small to spin well in a full-size banger.
- How many come in a pack? Two.
- Do they need a spinner cap? A spinner cap gets the most out of them, but any directional cap will move them.
- Will the color fade? No. The opal is stable through normal torch and e-rig temperatures; just avoid dropping a cold pearl into a red-hot banger.
- How do I clean them? Soak in isopropyl alcohol and wipe dry.
- Is a banger included? No, pearls only.
