Description
This listing covers MJ Arsenal’s carb cap styles in one place — directional, flat, bubble, spinner and the mushroom variants — so you can match the cap to how your banger behaves. Directional caps steer airflow to one side, flat caps seal a bucket completely, bubble caps fit rounded chambers, and spinner caps drive terp pearls in a circle.
Why it stands out
- Five cap styles: directional, flat, bubble, spinner and mushroom
- Directional cap measures 30mm across a 1″ x 1.2″ body
- Quartz and glass construction depending on style
- Choose the cap by how you dab, not just how it looks
Specifications
- Styles: Directional, Flat, Bubble, Spinner, Mushroom – Bubble, Mushroom – Spinner
- Directional dimensions: 1″ x 1.2″, 30mm width
- Material: Quartz / borosilicate glass depending on style
Compatibility
Bubble and mushroom caps require a rounded bucket opening; flat and directional caps fit standard flat-top bangers.
Care
Wipe the underside warm — the cap collects more residue than the bucket rim.
