Roller bottles, also known as roller-ball bottle, is a relatively common packaging bottle at present and is widely used by people. The body of the roller bottle is usually made of plastic and glass. Roller bottles usually have a small capacity, and a ball is installed at the mouth of the bottle so that people can apply it evenly, prevent liquid leakage, and also have a massage effect. There are two kinds of balls on the head of the roller bottle: plastic and steel balls. Generally, steel balls are used for cosmetic eye cream bottles, while plastics are used for cheap products such as lipsticks, depending on the price of the product.

For use in some designated locations, roll-on products appear to be more professional. Among them, plastic roll-on bottles are used for eye cream, which can be directly applied to the skin around the eyes. It can be applied evenly and has a massage effect, which helps to eliminate eye wrinkles and eye fatigue; the cool touch of glass beads and steel balls can help eliminate eye puffiness and they are easy to use.

The packaging form of perfume called "rolling beads" on the market is actually named according to the characteristics of the bottle mouth structure of the perfume bottle. The bottle type used in this packaging form is generally a cylindrical transparent glass perfume roller bottle with a smaller size, and the bottle mouth is covered with a "polyethylene roll-on inner cap", which is covered with a plastic or metal screw cap.
