50ml 18-400 Flint Clear Glass Dropper Bottle

The small capacity and specifically the 18mm neck finish are distinctive features of dropper bottles. Dropper bottle sizes typically range between 5 ml to 30 ml due to the product being composed of a high concentration of ingredients such as essential oils. Since the end user would only need small dosages of the product at a time, dropper bottles are often paired with continuous thread caps, droppers, sprayers and phenolic caps.
