Perfume Studio Set of White Frosted Roll Ons with White Caps. 10.5 ml - 5 Units. Includes 5 interchangeable plastic and 5 metal ball roller tops to use depending on your application.

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.
