The Early Bird Serin RBA MTL Kit is designed to transform your Serin RBA into a more refined mouth-to-lung setup. This accessory bundle includes an MTL wicking sleeve, integrated MTL drip tip, airflow chamber insert, and three smaller airflow pins (0.8mm, 1.0mm, and 1.2mm) to create a noticeably tighter draw.
While the standard Serin RBA features airflow pins starting at 1.5mm, this kit allows for a more restricted inhale — ideal for nic salts and higher-resistance builds. If you’re aiming for an authentic, cigarette-style MTL experience, this kit provides all the components needed to fine-tune your setup.
The standard Serin RBA covers MTL to DTL with air pins from 1.5mm to 3.5mm. This MTL kit goes tighter with 0.8mm, 1.0mm, and 1.2mm pins for a real restricted draw. The MTL chamber insert and wicking sleeve are designed to work together for concentrated flavour on tighter builds. If you already own the Serin RBA and want to go full MTL, this kit converts it completely.

- 1 x MTL Wicking Sleeve
- 1 x MTL Integrated Drip Tip
