1 oz dropper Perfect fit for the smaller oil bottles.

Great accessory! I hate getting oil where there is no delivery method other than an open bottle. Trying to poor just a couple of drops into your hand is ridiculous. There droppers help me to regulate such product.

I wish everyone used this kind of dropper! As silly as it may sound, I think it is a sin to put a restrictor top in a glass bottle. By the time you get any amount of oil out it's ran down your hand an onto the sink. I love these droppers because when you use them they fill the tube with oil. Thus I control the amount of oil that I use. And on most glass bottles once I remove the restrictor the dropper makes a perfect replacement lid.

Perfect size I have a fee smaller bottles of oil with out a cap that limits the amt dispensed. This fits perfectly and distributes the exact amy each use.

Great Good for the small bottles but not the bigger ones.
