Review (1/5): All of these leak and will not hold 15ml with dropper inserted
UPDATE: THESE LEAK! At first I thought I had spilled a little over the top when putting the cap on (the label got oily), but after a few days of moving these bottles around, all of them have leaked. Total waste of oils. Also, they will only hold about 11-12ml if you intend to use the included dropper.
