You can then neatly dispense the product by applying pressure to the bottle. Next, press the cap back down neatly to store your product. The push-close lid makes for no-mess dispensing and reduces spillage. This 20-410 black polypropylene (PP) plastic disc top cap has smooth PP wall disc and smooth outside round skirt.
