NPA and WAGG bottle tops

[CollegeStudent]

My NPA

and WAGG have something like a dropper in their tops, but not sure how that works. Not about to turn the bottle

upside down to figure it out myself either. I have been gently prying the stopper off and using an eyedropper to

get the NPA for my JB mix. Can I leave this dropper off permanently? Or will that mess up the seal on the bottle

and it will leak?

Well I figured out it does drip, and from the looks of it taking it off will remove the seal.

Yeah

taking it out makes it leak, I did a test with water a while ago.
