Review on Convenient Refillable Containers: Your Must-Have Essential Cleaning Aromatherapy Travel Accessories by Sandra Landgrebe

I would give 5 stars. The glass is excellent. Blue and decent quality. I'm not sure how far they will survive a fall, but since they're glass you can't expect much. That means I can't tell how thick the glass is. But the real problem I have is that the small bottle I bought the set for ONLY has a "water-like viscosity" atomizer tip. They may include an oil spray tip. The large bottle works great with oils. However, with a small bottle, the oil hardly flows out of the hole, because only the size fogs.
