Refill cap fits on top of 60 mL Chubby Gorilila bottles, adding a 510 threaded tip to allow users to directly refill their bottom feed squonk bottles without ever having to remove their squonk bottles from their mod! Just remove your atomizer, screw the 510 threaded tip on to the mod's atomizer connector, and squeeze to fill!
Metal revolver cap also doubles as a 510 atomizer stand!
User Tip: Turn the mod upside down first, then squeeze (and hold) the squonk bottle before attaching the squonk refill cap. Once the juice supply is attached, turn the mod right side up, and slowly squeeze your Chubby Gorilla bottle while slowly releasing your squonk bottle. The combination of positive pressure on the Chubby Gorilla bottle combined with the negative vacuum pressure on the squonk bottle will allow the juice to flow freely.
