Great to replace the fitments in all your dram and 10ml rollerball bottles that we sell. when you change oil blends, change to a metal roller ball! they snap in easily and roll well! THESE ARE PREMIUM ROLLERBALLS
These Fitments, although the highest quality, may still not work with Certain Essential Oils or Blends, such as those that contain Frankincense or Citrus Oils. They may dissolve the seal on the rollerball assembly, but we don't expect that will happen.. Also, do not place carrier oils in bottles using these rollers. the balls may pop out. For best usage, these should only carry pure perfume oils, and pure essential oils.
We advise testing each oil blend before filling your bottles.
