Great roller bottles. Great value.
These roller bottles are a great value. I've tried many brands, and though these cost less, they perform just as well. The balls roll evenly, in turn evenly distributing the oil without causing runs/leaks. All six rollers fit in the bottles (I usually have at least one set that doesn't match up well),-yet can be easily popped out if needed, the lids screw on tightly & securely, and the cobalt blue color glass helps protect essential oils from light. They serve their purpose well for a price I don't mind paying.
