Review on Bottles Refillable Aromatherapy Essential Container by Heather Johnson

They're great for small batches of essential oils that we don't use regularly and for samples. We have them everywhere and I love how portable they are. 1/2 inch labels from my label printer also fit perfectly. Some balls don't roll as easily as others, but I've only had to throw out one or two of the last 4 packs, so it's not that big of a deal. Roller tips are very tight fitting so refilling them when needed can be a bit difficult.
