20-400 Silver PP Plastic 3.5in Smooth Dropper Caps
Precise dispensing is made easy with these Polypropylene Dropper Caps. Dip tube is constructed of glass. All bulbs are rubber. Natural rubber bulb droppers function best with water and alcohol based products and is not ideal for oil-based products. If used with essential oils, this dropper should be used for dispensing only and not long-term storage as the oils can deteriorate the dropper’s natural rubber bulb. Please test product for compatibility with application before going into production. Material and color compatibility varies by end use product.
