Glass Dropper Medicine 1ml, Teenitor Essential Oils Eye Dropper Pipette Dropper with Black Suction Bulb, Straight-Tip Calibrated Droppers for Medicine Art Liquid Plant Nutrients 20 Pack

Works as expected. My original one was used for linseed oil measuring related to oil painting. Unfortunately, I did not get the eyedropper rinsed out with soapy water so the oil set and blocked the eyedropper that I needed for a course. I ordered these and they were here before I needed them and work perfectly. Only needed one but if I screw up once again, there are plenty of replacements. These are good quality glass, markings, rubber bulb. It is just an eyedropper but when you need one...

These eyedroppers work very well for me. I can't attest to the precise accuracy of their measurement markings, but for things that don't need precise, exact measuring beyond number of drops, they work well. Some of the measurement markings are partial, or slightly displaced, as if by movement of the glass during the printing process, but that doesn't bother me. I use these to mix fountain pen ink, and I'm very happy that so many came in the package. They were well cushioned around the bag, and even though the individual glass pipes were all together instead of individually wrapped, none of them were broken. The rubber suction bulbs were in perfect condition, smooth and springy, with no cracking or signs of age. Also, there were a matching number of bulbs to glass eyedropper pipes, with no extra or missing pieces. The only thing I don't like is the size of the bulbs, which make it necessary to squeeze the bulb quite hard in order to suction enough liquid to get up to the 1ml mark, and it won't go much further than that. It made me nervous when mixing ink because I was afraid I'd lose my grip or my fingers would slip or something and ink would get thrown everywhere. Overall, I am happy with this purchase. I will buy this product again if I need to, but I think these will last me for a very long time.

Great function and quality build.

An item I don't use very often, but great to have available on-hand.

These do not squeeze well at all.
