25 Pcs 1ML Amber Glass Bottles: Ideal Mini Essential Oil Vials for Aromatherapy, Cologne Samples, and Perfume Storage Review

Large size for oil sampling. After installing the plastic part, no oil will leak out. You should leave the bottle open most of the time to pour liquid and also leave it on in case of a leak.

Great little sample bottles but about 5 of them were completely broken in the little bag. I'm glad I noticed before the glass hit my finger. It doesn't look like the outer packaging as all my other glass items have been fine.

It's good to taste oils, but the oil doesn't flow out of the eyedropper! Makes it harder when trying to count your drops.

I bought these to decant perfume oils for personal use. The bottles work well, the dropper inserts are functional. Some of the inserts leak very easily, which may be related to the thickness of the perfume oil, but none of the caps leak. My biggest complaint is that the vials are not 1ml but 1.5ml. That's fine with me as they are for personal use but if you buy them for measured samples or a decent circle see yours Bottles half empty when you only fill them with 1ml.
