PLEASE READ! ****Essential Oils are very concentrated substances, and shouldn’t be used at concentrations above 40% in a roll-on bottle, as the oil can have a solvent effect on roller-ball housings. ALSO- FRACTIONATED COCONUT OIL (FCO) IS NOT RECOMMENDED WITH STEEL ROLLERS, any other type of Carrier Oil will work. For FCO, Use plastic or Glass roller-balls. Most medicinal uses of essential oils don’t require full-strength either.
Note- Caps should not be over-tightened! If you can’t push the roll-on into the bottle, try this: Hold the bottle on a solid surface with one hand. Place the roll-on insert into the bottle. Screw the cap (clock-wise) while applying DOWNWARD pressure.
