1. Material and Design Suggestions
Material: PET or PP plastic is recommended (resistant to corrosion, lightweight, and recyclable).
Pump head design: A fine foam model (with a foaming net structure) is recommended to prevent liquid from flowing out directly.
Transparency: A semi-transparent bottle body is convenient for observing the remaining volume and helps prevent the situation where it is not noticed until it is completely used up.

2. Usage Tips
Dilution Ratio: It is recommended to use a 1:1 or 1:2 ratio of facial cleanser to water (adjust according to the consistency of the product), and shake well before use.
Cleaning and Maintenance: Disassemble the pump head every month for cleaning to prevent residue from clogging (especially for soap-based products). Compatibility: It can be used for liquid cleaning agents such as shampoo and body wash, but be sure to match the viscosity.
