Perfume Studio® Set of Emerald Green Glass Roll Ons with Metal Ball Applicators - Ideal for Essential Oil - 10.4 ml (3, Black Cap)

Perfume Studio Set of Emerald Green Glass Roll Ons With Metal Ball Applicators - 10.4 ml, with choice of 3, 6 or 9 Units with either black or white caps. Please make sure you use the metal ball rollers with only pure uncut oils. Blended oils using carrier oils such as fractionated coconut oils act as a lubricant and will force your metal ball top pop out. For these blends, we recommend using plastic ball roller tops.
