4 Pack Glass Dropper Bottle with Inner Plug and Label (60 ml, Green)

The bottles are beautiful and look very nice as containers for homemade bitters. There were two things that could be improved relative to other bottles I've purchased:
1. Make the dropper pipette from glass, not plastic. Plastic is flimsy.
2. The rubber suction cap should be a little larger. The current cap only draws about 1/4 of the pipette's volume.
I did not get the plastic bottle-sealing inserts into which the dropper is inserted with my bottles. It provides an extra level of sealing which, for something like aromatic bitters, is important.

Dropper is to awkward for E-Juice. You will find it's not like the old e-juice bottles with droppers when you purchased from a vape shop. Not the same at all....don't bother if you thought you can use these in that manner.
