AOZITA Set of 4, 1 oz Eye Dropper Bottles with 1 Stainless Steel Funnels & 4 Labels - 30ml Thick Dark Amber Glass Tincture Bottles - Leakproof Essential Oils Bottle for Storage and Travel

Perfectly great for what I used them for.

This is just what I needed for my herbal lemon balm tincture, I’ll be purchasing more!!

I had 2 expensive bottles of iodine. Both rubber caps on the droppers cracked and no longer suctioned or released the drops. I was able to replace the bad ones with these and was able to save and use the iodine.

The main concern for me was leakage. I use these for mineral oil and different grades of alcohol, none of which may stand perfectly upright in my electronics tool bag. I tested these by using a bottle full of water, and then turning them upside down for 24 hours. They didnt leak. Be sure you tighten the tops down enough, otherwise the rubber seal may not engage fully which would allow leakage. I have no idea how long he rubber (or whatever it is) seal will last, but new, they dont leak.

I like these. Theyre small and great for what intend to use them for. The droppers work as they should. The included labels are also a nice touch. They were very well packaged and arrived whole.

No measurement markings, bad suction.
