EARLY BIRD SERIN RBA MOUTH TO LUNG KIT
Transform your Serin Boro RBA into a true mouth-to-lung (MTL) vaping setup with the Early Bird Serin Boro RBA MTL Kit. Designed for vapers who prefer a more restricted, cigarette-style draw, this specially engineered kit delivers a tighter airflow and enhanced flavour intensity, giving you full control over your MTL experience.
Whether you’re switching from a direct-to-lung style or simply want a smoother, more focused vape from your Serin RBA, this MTL Kit provides all the components you need for a precision-controlled inhale. With interchangeable MTL airflow pins and a dedicated internal chamber, this accessory shrinks the airflow path to produce a more traditional MTL feel, ideal for higher-resistance coils and flavour-forward builds.
Key Features
- Official MTL conversion kit for the Serin Boro RBA
- Tighter airflow control for true mouth-to-lung draws
- Interchangeable MTL airflow pins (0.8 / 1.0 / 1.2 mm) to fine-tune restriction
- Dedicated internal chamber and wicking sleeve for improved flavour and consistency
- Includes an MTL-specific drip tip designed for comfort and optimal draw
- Perfect for 50/50 e-liquids and higher-resistance builds
The Serin RBA is already a top-airflow flavour performer — but with this MTL Kit, you can tailor your vaping experience to your preference. The reduced chamber volume and narrower airflow make a significant difference in vapour density and flavour focus, giving you a satisfying, cigarette-like draw without sacrificing the quality you expect from Early Bird.
Ideal for vapers who enjoy mouth-to-lung inhaling, nicotine salts, or balanced freebase juices, this kit lets you refine your Serin RBA to suit a restricted, flavour-centric vape.
