24, 1 oz Dropper Bottles for Essential Oils with 6 Stainless Steel Funnels & 1 Long Glass Dropper - 30ml Amber Glass Bottles with Eye Droppers - Tincture Bottles, Leak Proof Travel Bottles for Liquids

It came exactly as described. It has a lot of funnels, the two long eyedroppers are very convenient for filling bottles to the right amount. The bottles are very durable, the seal is perfect, no leaks, I carry one in my purse with no worries of it leaking. These bottles are very easy to use and to fill with any kind of liquid. The eyedroppers are a good design, they reach the bottom of the bottle and they're of good quality. Overall the use and functionality of the bottles and the eye droppers are exactly as they describe they are. No disappointments here. The labels are cute too, good for home use but if you are using these bottles professionally you may want to use your own labels.

The bottles themselves are of good quality. Thickness, weight, coloration are approximately the same as a bottle from a reputable apothecary supplier. Foundry markings differ, so obviously not the same factory, but equivalent quality glass. I have not performed cross-polarized measurement of stress in the glass, but that would be overkill here. The caps are acceptable. They are made of a slightly softer plastic than are some of my higher-end bottles, and the rubber used for the dropper is less dense than that of the nicer bottles. It more readily absorbs/passes limonene and ketones than does the denser rubber. Small and volatile compounds will escape these at a greater rate than with nicer rubber. Neither the rubber or plastic seemed particularly vulnerable to acetone or limonene. The dropper stems are of decent quality, and do reach quite close to the bottom. One of the stems arrived broken. Packaging was good. Bottles were separated by cardboard dividers, and none of the bottles were in direct contact with each other. The cardboard dividers were suitably thick to absorb vibration. The pack-ins are nice. The funnels are OK, but I am unsure of what they are made of and they had a questionable smell when cleaned with ethanol. I probably will not use them for anything I particularly care about. The labels are a nice addition, as are the included standalone droppers. The standalone droppers are labeled up to 1mL in .25mL increments, and one has an angled tip. Notably, the bulbs on these two droppers if of a higher quality than that which is on the lids. I have not measured the accuracy of the droppers.

Muy buenos

I will definitely be buying more of these little bottles

Great for my tincture.
