Comfort Axis Graduated Glass Droppers Black for 1 oz Round Bottles - 3 Pack

I have been buying Boston Eye Droppers for a while. I have learned when I receive the package to look at every eye dropper to make sure the the tips do not have defects and that the Dropper Top does not have the glass tube protruding to far into the Dropper. When I received this package, I immediately checked these points for defects. All 12 were perfect. I am a happy customer:)

I dislike the fact that as other reviews have stated the rubber bulb does not allow the calibrated/graduated glass dropper to fill completely. You can not get 1.0 ml. These should be sold as 0.5 ml calibrated/graduated droppers. This company does not indicate that you "can" or "cannot" fill to the 1.0 ml marking so they escape false marketing. Just know that you will achieve a 0.5 ml suction yet are paying for the markings on glass droppers indicating 1.0 ml.

The suction power is poor which makes them difficult to fill. It's also hard to get an accurate reading because of that same problem. If you tip them to the side when they're filled they leak around the rubber stopper.

I like to add a drop of abstract to my water And coffee to switch it up a little bit and give me a little bit of flavor. These eye droppers worked perfect.

Nice design, looks great, but the bulb does not have enough suction to draw liquid (water) through the full column. It's a 0.5 ml to 0.6 ml dropper, not a full 1.0 ml.
