Perfume Studio Set of White Frosted Glass Roll On Bottles with White Caps and Interchangeable Metal/Plastic Balls
IMPORTANT: Only use the metal balls with pure uncut essential or perfume oils. If your oils are blended with any carrier oils such as coconut, jojoba, almond, etc., the metal ball will pop out of the housing. For these blends and type of lubricant oils, use the plastic balls instead. If the metal ball pops out, then you're using a blend that contains these lubricant type oils. METAL BALLS ARE ONLY FOR 100% PURE, UNCUT OILS.
GUARANTEED AGAINST LEAKS. These Perfume Studio essential oil Roll ons have been factory and field tested for leaks with pure, uncut essential oils.
