Review on Convenient Refillable Aromatherapy Rollerball Bottles: The Essential Way to Enhance Your Well-being by Linda Wiley

I honestly like it. I was a bit worried about the quality but I've already used about half the bottles and they all fit very well for their size. The smaller the bottle, the more difficult it is to squeeze out the oil, but the oil shouldn't spill either. So far I've used them with thick and thin blends/oils and they don't leak and distribute the oil well. Sometimes you have to wait a second for the oil to come out, but it won't break, you just have to be patient. Will definitely be ordering more when they run out! They're a great size for specific formulas and on-the-go bottles when you just want to drop your bag/pack and go.
