Review title is Caps Aren't the Greatest [SEP] I like these bottles and like the size, but the caps are kind of leaky. Even though the cap is screwed on tight, whenever I use them to disperse essential oils, the oils drip out of the opposite side of the spout then down the bottle. Then when you set the bottle down, it leaves an oil ring. Its messy. I have to have some kind of a coaster to put them on every time I use them.
