Caution

We recommend that these serum pumps be used with water based serums (serums with more water than oil) instead of oil based serums (serums with more oil than water) as the latter tends to leak a little during storage.

Important Notice: Our 18mm closures, including pumps and sprays, are designed for broad compatibility across a range of containers, but are not specifically engineered for use with glass bottles. While many customers use them successfully with 18mm glass bottles, some leakage may occur. We recommend testing compatibility with your specific packaging and product to ensure optimal performance.

Usage Recommendation: For optimal performance, we recommend using these serum pumps with water-based formulations (i.e., serums with a higher water content than oil). Oil-rich formulations may be more prone to minor leakage during storage due to their viscosity and interaction with the pump components.
