These small clear PET round bottles are available in 1/2 oz or 1 oz sizes with black polypropylene twist top closures. The twist top caps allow for convenient and controlled dispensing of the bottle's contents with a simple twist of the cap to expose the cap's orifice. When not in use, simply twist the cap in the opposite direction to lock it into place and prevent leakage. These clear plastic bottles could be used to package a variety of products such as paints, inks, glues and much more.
