Review on TecUnite Droppers: Precision-Calibrated 🌡️ Essential Oil Droppers for Accurate Dispensing by Kyle Awasthi

Easy to use, good price, good quality. I mark the sandwich bag with a magic marker, then after using a specific essential oil or other item for the first time, I place the used dropper in the bag for later use. Draw as much oil as possible into the dropper, turn the dropper upside down, then squeeze the balloon to deflate and hold the balloon, reinsert and pull again. Squeeze out what you don't need to get a good measurement. I like them because you can have a separate eyedropper for each item you use. I would buy again.
