A: According to brand needs, logos, patterns, and texts can be printed on the bottle body, and specific colors and cap styles can also be customized to make the vacuum bottle better highlight the brand characteristics.

A: There is a minimum order quantity for purchasing hongyun's vacuum bottles, and the specific value depends on product specifications and customization requirements. Generally, the larger the purchase quantity, the more favorable the unit price. We will provide corresponding tiered prices according to the actual order quantity. For small-batch purchases, you can check the regular stock products. Some stocks have a low minimum order quantity, providing you with more choices.

A: For a simple test, fill the bottle with about 1/3 capacity of water, close the lid tightly, press the pump head several times to expel air, then invert the bottle and let it stand for 5-10 minutes. If no water leaks, it indicates that the basic airtightness is good. For a precise check, observe the piston movement during use: when pressing the pump head to take the contents, the piston should move up smoothly without jamming; after stopping pressing, there is no sudden "sucking" sound and obvious air backflow, indicating that the airtightness is stable.

In addition, if the liquid is left standing for 2-3 days and there is a significant reduction without being used, there may be an airtightness problem. In this case, please contact us, and we will inspect or replace it to ensure proper handling.

A: hongyun's vacuum bottles have a wide range of applications. They are suitable for liquid products such as serums, toners, and lotions, as well as paste-like products such as face creams, eye creams, and foundations. However, overly thick products or those containing a large number of particles may affect the normal operation of the vacuum device, so it is recommended to conduct a small-dose test before use. We are always committed to providing suitable packaging solutions for different types of cosmetics.
