I use these for giving my pets medicine or when I have to dose them homepathically. They don't hold a lot, but they're small and thin, so they're easy to get into their mouth. Also, they're completely plastic, so I don't have to worry about hurting them. And they can't bite or break them. MUCH better than a glass eye dropper.
Measurements on the outside are easy to read. They're easy to fill Definitely a product that I needed. AND, if you're not using them for anything caustic, you can easily clean and re-use them.
They do NOT come with needles!
