The material used is high - quality PP. It is not only non - toxic and odorless, but also has excellent corrosion resistance and impact resistance. Even with long - term use, it is not easy to wear or deform, ensuring high stability. The 28/410 specification is suitable for a variety of bottle bodies. Whether it is a refill bottle or an original bottle, it can be easily "adapted", allowing old bottles to be equipped with a new "pump".

The unique left - right switch design is a major highlight of this product. With a gentle twist to the left or right, you can easily turn on or off the pump head. This is not only simple to operate, but also can effectively prevent liquid waste caused by accidental pressing. At the same time, the buckle is like a loyal guard. It fits tightly to form a stable sealing structure. Even during bumpy travels, it can completely prevent accidental liquid leakage, allowing you to be worry - free when you are out.

In terms of usage scenarios, it is suitable for various liquid or paste - like cosmetics such as lotions, creams, and shampoos. Whether it is for precise dosage control during daily home skincare or for dividing large - bottle cosmetics when traveling, it can perform perfectly, making every beauty and skincare process of yours more easy and convenient.
