Review on 💧 Refillable Perfume Bottle Travel: Convenient Roll-On Solution for Fragrance On-The-Go by Kimberly Jackson

Only one of the bottles is good. The bottles consist of three separate parts: glass bottle, cap and rollerball. The rolling ball unit does not fit in a regular bottle because the bottle neck is too small. The rolling balls didn't spin well or leak oil, so I stuck a pin between the ball and the rim and ran it all over the ball to loosen it up a bit. I could skip some oil after that, but it's still not as good as the store-bought bottle of oil that's already in there.
