The AUGVAPE Occula RDA is a cooperation between AUGVAPE and TWISTED MESSES. It is a perfectly designed rebuildable tank atomizer with innovative internal-post clamp design. It features dual posts with big M3 Screws that make the deck very easy to inset coils for user. And it is compatible with both single and dual coil building. The top cap dome design reduces chamber space and brings better throat hit. It also comes with a BF pin, so it is compatible with most squonker MODs.
