This container is fitted with a high-performance full-plastic flat top cap with a multi-layer composite sealing structure for stable and long-lasting use. The outer cap is constructed from durable ABS material, offering high hardness, excellent wear resistance and strong structural stability to maintain a neat and flawless appearance.
