Cornucopia Brands (24 Pack) Aromatherapy Essential Oil Bottles are great for an essential oil enthusiast. This set of 24 amber essential oil bottles are great for storing, sharing and taking along essential oils. I've told my family about these different oils and these bottles are a great way to share with them. With this set of bottles, it includes twelve 2ml bottles and twelve 1ml bottles. Each bottle comes complete with a screw on lid and orfice reducer. The amber color of the bottles help to keep light out in order to prolong the life of essential oils scent and health benefits. The orfice reducers keep oil pouring regulated and help to reduce accidental waste or spillage. These are a very sturdy, durable set of bottles. Very convenient and easy to fill. If you're an essential oil fanatic, I highly recommend picking up this pack of bottles. I received these bottles in return for my honest review.
