The 405 series is the largest dosage in the lotion-pump range at 4.5 ml per stroke, made for body wash, shampoo, hair mask and bath gel. Its outer-spring construction keeps metal out of the fluid path — a requirement for sulfate-based and low-pH formulas — while the wide chamber maintains a smooth, even stroke even with thick gels. The collar is available for 28/410 and 33/410 necks, with smooth or custom finishes and full decoration options.
