Chubby Gorilla Black Unicorn Bottle 60ml is designed specifically for e-liquid unlike others, they feature a soft squeeze pet bottle that doesn't shatter like glass bottles, the mouth of the bottle is wider making it easier to fill, the dripper base fits tighter to avoid leaks and the built-in drip tip is narrow to avoid over drip. The CPC-compliant child resistance cap and tamper-evident seal are engineered for safety and assurance.
