Review (5/5): I have ordered several times from this seller (4x), will definitely order again! Never had an issue with a single bottle yet!
So I guess Amazon won't let me review all the other 15 ml roller bottles I've received from this seller (it's been over six months), but five stars for the blue, green, and amber ones I've ordered. I use these for essential oil blends and I do try to keep them upright as much as possible but all are diluted with a carrier oils and of those I've given to friends and family, I'm not sure if they're careful to store them upright or not. Either way, I've heard no complaints, and I have no complaints. All of the roller ball lids fit perfectly, don't leak, and are easy to remove for refilling.
