4oz Black Glass Tube Dropper with 22-400 neck

We love our very popular 22-400 Black Glass Tube Dropper as they are one of the easiest ways to disperse your products. This 22-400 Glass Dropper works with our 4oz Glass Bottles that feature a 22-400 neck, and easily screws onto the glass bottle to give a stylish look. Release your product drop by drop with the silicone bulb.
