Serin MTL Kit by Early Bird

Serin RBA MTL Kit – True MTL Conversion by Early Bird

The Serin RBA MTL Kit converts your Serin RBA into a dedicated Mouth-to-Lung setup. This accessory pack adds tighter airflow, focused chamber reduction, and improved wicking control for a true cigarette-style draw.

It targets nic salts, higher-resistance coils, and flavor-focused builds.

Precision MTL Airflow Control

The kit includes three MTL air pins: 0.8mm, 1.0mm, and 1.2mm. These sizes create a noticeably tighter draw than the standard Serin pins, which start at 1.5mm.

Swap pins quickly to match coil resistance, e-liquid strength, or personal preference.

Focused Chamber & Wicking System

An MTL airflow chamber insert compresses vapor space for stronger flavor concentration. The MTL wicking sleeve improves juice control on tighter builds and reduces oversaturation.

Together, these parts create a smooth, restricted inhale with clean flavor delivery.

---

Integrated Drip Tip for MTL Comfort

The included MTL integrated drip tip narrows the vapor path and improves lip feel. This design enhances draw restriction while keeping the setup compact and balanced.

Why Choose the Serin RBA MTL Kit?

The standard Serin RBA spans MTL to DTL. This kit pushes airflow tighter for a true restricted draw. The chamber insert and wicking sleeve work together to intensify flavor on small coils.

If you already own the Serin RBA and want full MTL performance, this kit completes the conversion.
