The 105 series is a compact 1.0 ml outer-spring lotion pump built for small-dose skincare — toners, essences and travel-size serums. Its short body and low actuator keep the bottle silhouette clean, while the outer-spring design keeps the metal spring outside the fluid path. Each stroke delivers a fixed 1.0 ml dose, so a 100 ml bottle dispenses roughly 100 pumps with little waste. Moulded in PP with a smooth collar, the pump takes custom colour matching, silk-screen or hot-stamp decoration, and ships with a matching overcap.
