Calaso Ribbed 18-400 Serum Pump 0.1cc

What this packaging is

Precision-dosed at 0.1cc per stroke, the Ribbed 18-400 Serum Pump from Calaso pairs a ribbed PP collar with a glossy white finish for a look that feels considered without being overdone. The 18-400 thread fit opens it up to a wide range of glass and plastic bottle formats — useful across body lotion, body oil, hand cream, face cleanser, shampoo, and body wash. Manufactured in the Netherlands, it reflects European closure craft: tight tolerances, clean aesthetics, and consistent pump performance at scale. The long dip tube handles low-viscosity liquids cleanly, making this an easy, reliable choice for brands building cohesive pump-bottle lines.

Why brands choose this

• Controlled 0.1cc dosing protects formula integrity: At exactly 0.1cc per stroke, this pump prevents over-dispensing — a real advantage for higher-cost serums, oils, and concentrated cleansers where dose control directly affects perceived value and product longevity for the consumer.
• 18-400 thread opens up a wide bottle roster: The 18/400 neck finish is one of the most widely used standards in body and skincare packaging, meaning brands can source this pump once and deploy it across multiple bottle shapes and sizes without re-engineering their component stack.
• MOQ of 1 unit makes it accessible for any scale: Whether you're developing a new SKU, running a small-batch launch, or testing a formulation, an MOQ of 1 removes the usual upfront commitment barrier — rare for a finished pump component and genuinely useful for indie brands and product developers early in the process.
