Calaso Smooth 18-400 PP Sprayer

What this packaging is

An 18/400 thread fit and fine-mist nozzle make this PP sprayer a natural match for room sprays and hair care formats where precision dispensing matters. The Smooth 18-400 PP Sprayer features a ribbed collar for secure bottle attachment, a smooth exterior finish, and a slightly tapered nozzle designed for consistent spray delivery. Made to order with an MOQ of just one unit — genuinely rare in component sourcing — this sprayer opens the door for indie brands, sampling programs, and limited-edition launches without heavy upfront commitment. Pair it with the right bottle and it quietly elevates everyday formats into something shelf-worthy.

Why brands choose this

• MOQ of one: real accessibility for small-scale sourcing: An MOQ of 1 unit is nearly unheard of in sprayer components — it removes the inventory risk that typically blocks small brands from testing new formats, making this a low-friction option for sampling, prototyping, or limited-edition runs.
• Fit-first design that reduces compatibility headaches: The 18/400 thread spec is a widely used neck finish across room spray and hair care bottle formats, meaning less guesswork when matching components — and faster development timelines when you already know your bottle neck size.
• Fine-mist delivery matches the ritual, not just the category: Room sprays and hair mists are increasingly experience-led products — consumers expect a diffuse, even spray. The tapered nozzle on this sprayer is built for exactly that kind of controlled, fine-mist application that matches the sensory expectation of the format.
