Review on Rollerball Essential Refillable Aromatherapy Randomly by Tony Bennett

These bottles are absolutely beautiful (and made of glass!) but unfortunately the rolls are too small for essential oils. The reels spin, but no oil comes out. Very sad! Based on other reviews the quality standards may be loose with some working, some falling out and some being too tight? heh I think it's like playing roulette. All the ones I tried in this order were too heavy to dispense essential oils in a carrier with coconut oil, maybe they would work for ephemeral perfume samples?
