Portability: Both sizes are compact and travel-friendly, allowing users to easily carry them in purses, backpacks, or travel bags. The smaller 30ml size is particularly convenient for on-the-go touch-ups, while the larger 100ml size provides ample product for longer trips or extended use.

Convenience: With smaller bottles, users can conveniently carry their favorite lotion or serum wherever they go, ensuring that they have access to skincare products whenever they need them. The larger 100ml size reduces the frequency of repurchasing, providing more convenience in terms of restocking.
