18-400 Bulb Dropper

What this packaging is

Precision dispensing in a glossy white finish — the Calaso 18-400 Bulb Dropper is a PP dropper closure built for face serums and hair oils that demand controlled, drop-by-drop application. The smooth collar and ball-shaped tip work together to minimize mess and maximize dose accuracy, while the 18/400 neck finish pairs cleanly with compatible glass pipettes for a fully cohesive component set. Backed by Calaso's European manufacturing heritage, this dropper brings a level of finish quality that reads premium on-shelf. With accessible minimums of 2,000 units, it's a practical entry point for emerging brands or limited-edition launches in the prestige skincare and haircare space.

Why brands choose this

• Dose-control design that matches the serum ritual: The ball-shaped tip and smooth collar deliver the kind of precise, drop-by-drop dispensing that serum and hair oil consumers expect — reducing waste, preventing over-application, and reinforcing the intentional, clinical feel that's driving growth in the prestige skincare segment.
• Complete component pairing reduces supplier complexity: The 18-400 neck finish is spec'd to pair directly with compatible glass pipettes, meaning your dropper closure and pipette come from a single coordinated system — fewer vendor touchpoints, faster fit confirmation, and less risk of compatibility issues during development.
• Accessible 2,000-unit minimums built for emerging brands: At a 2,000-unit MOQ, this dropper is genuinely workable for indie skincare and haircare brands launching a hero serum or testing a new hair oil SKU — low enough to manage cash flow without locking into volume you haven't validated yet.
