Black PP 18-400 Ribbed Skirt CRC Dropper assembly glass pipette
The M660BK is a black PP 18-400 ribbed skirt child-resistant dropper assembly with rubber bulb and glass pipette (fits 1/2 oz bottle). Dropper assemblies are composed of a number of parts: the cap, the bulb and the pipette (tube). The length of the pipette is approximately 65.28 mm (2.57 inches). Dropper assemblies are used with liquids that require precision and intricacy when using the product. This closure has been equipped with a child-resistant feature. Polypropylene (PP) is marked with the resin identification code of 5. PP is less flexible than LDPE, somewhat stiffer than other plastics, reasonably economical, and can be translucent, opaque, or of any color. PP has very good resistance to fatigue, and has an extremely high melting point (320 degrees Fahrenheit or 160 degrees Celsius).
