*THIS IS THE RBA ONLY - BORO TANK IS NOT INCLUDED*
Check out Early Bird's boro tank - the Compass Boro Tank

The Serin RBA is Early Bird’s first rebuildable bridge for Boro tanks. It gives users full control over coils, airflow, and flavor. The design targets both beginners and experienced builders who want flexibility without complexity.

Because of its compact bridge format, the Serin RBA fits easily into most Boro AIO setups. Please note, this is the RBA only. Empty Boro Tank is NOT included.

Flexible Airflow from MTL to DTL

The Serin RBA includes five interchangeable air pins. Sizes range from 1.5mm to 3.5mm. Start tight for MTL or open it up for restricted DTL.

You can swap pins in seconds. This airflow range suits different coils, liquids, and personal preferences. An optional Serin MTL Kit allows an even tighter draw.

Simple Single-Coil Build Deck

The single-coil deck keeps building straightforward. Coil installation feels open and uncluttered. Wicking stays simple thanks to the anti-leak channel design.

You can wick slightly looser without worrying about seepage into your tank.

---

Top-Airflow for Clean Flavor

Air enters from the top and travels down to the coil. This layout reduces leaks and keeps the chamber drier than bottom-airflow designs.

As a result, flavor remains concentrated and consistent with every draw.

---

Broad Boro Compatibility

The Serin RBA fits most Boro tanks and AIO mods that accept bridges. It also works with premade Boro coils if you prefer convenience over wrapping your own builds.

This compatibility makes the Serin a strong upgrade for stock-coil users.
